China supplier Best Price Angular Contact Ball Bearing 7308AC 7309AC 7310AC 7311AC for Machine Tool Spindle, High Frequency Motor bearing driver kit

Product Description

The characteristic of angular contact bearing is that it can bear both radial load and single axial load. The larger the contact Angle, the larger the axial load, the smaller the contact Angle, the smaller the axial load. Conversely, the smaller the contact Angle, the greater the ability to bear radial loads, and the more suitable for high-speed applications. According to different working conditions, it can be combined in a variety of ways to obtain different radial and axial load capacity, and meet the requirements of high speed and diameter, and high axial stiffness.

Angular contact ball bearing accuracy class includes dimensional tolerance and rotation accuracy. From low to high accuracy is expressed as P0(ordinary), P6(P6X), P5, P4, P2, in addition, P3, P7, P9 are also used in European and American brands to indicate accuracy levels, P3 is equivalent to level P6 of ISO and JS standards, P7 is equivalent to level P4, and P9 is equivalent to level P2.

FAQ

Why our bearing is better than other?
Material
We usually use bearing steel (GCr15), but many manufacturers only use softer carbon steel materials, so our bearings have higher hardness and longer service life.

Heat treatment
We have our own heat treatment plant and do not need to be outsourced. We use a slower speed and more stable temperature to effectively control the steel and increase the toughness and life of the steel.
Other small-scale bearing companies usually need to outsource. Many outsourcing factories only strengthen the hardness of the bearing surface due to cost factors, but the hardness inside is not enough, which is the reason why many bad bearings are easy to crack.

Precision
Our bearings can be controlled at a height accuracy of 0~-0.004mm, fast speed and smoothness.

Multiple grinding process
We grind the bearing many times, but others may grind it only once, so the chamfer of our bearing is very smooth.

In conclusion
We use high-quality materials and multiple grinding processes, so our bearings have the characteristics of high speed, low noise,high precision and long life.

Quality guarantee
we give our customers 1 year quality warrantee for the bearings.

rolling contact bearing

What are the potential challenges or limitations associated with using rolling contact bearings in various industries?

Rolling contact bearings offer numerous benefits and are widely used in various industries. However, there are certain challenges and limitations associated with their use. It is important to understand these potential issues to ensure proper application and mitigate any adverse effects. Here’s a detailed explanation of the challenges and limitations associated with using rolling contact bearings:

Load Capacity:

While rolling contact bearings are designed to handle substantial loads, there are limitations to their load capacity. Exceeding the specified load limits can lead to premature wear, increased friction, and potentially catastrophic failure. It is crucial to consider the expected loads in the application and select bearings with appropriate load ratings and configurations. In some high-load applications, alternative bearing types, such as spherical roller bearings or tapered roller bearings, may be more suitable to handle the specific load requirements.

Speed Limitations:

Rolling contact bearings have speed limitations that need to be considered in high-speed applications. At high rotational speeds, centrifugal forces can affect the performance and reliability of rolling contact bearings. The limitation is primarily due to factors such as the bearing’s internal clearance, cage design, lubrication, and the potential for increased heat generation. To overcome speed limitations, specialized high-speed bearings with improved designs and materials, such as ceramic balls or hybrid bearings, may be used in certain applications.

Maintenance and Lubrication:

Proper maintenance and lubrication are essential for the reliable operation of rolling contact bearings. Inadequate lubrication or improper maintenance practices can result in increased friction, heat buildup, and premature wear. It is important to follow the manufacturer’s recommendations for lubrication intervals, lubricant selection, and application methods. In some applications, such as high-temperature environments or extreme operating conditions, special considerations may be required to ensure effective lubrication and prevent bearing failure.

Environmental Factors:

Rolling contact bearings can be sensitive to certain environmental factors. Exposure to contaminants, such as dirt, dust, moisture, or aggressive chemicals, can lead to accelerated wear and corrosion. In industries where the operating environment is harsh or contaminated, additional protective measures, such as sealing arrangements or the use of specialized coatings, may be necessary to enhance the bearing’s resistance to environmental factors. It is important to evaluate the specific environmental conditions and select bearings that are suitable for the intended application.

Installation and Alignment:

Improper installation or misalignment of rolling contact bearings can result in reduced performance and premature failure. Achieving accurate alignment and proper fitment during installation is crucial. Misalignment can lead to increased friction, uneven load distribution, and potential damage to the bearing surfaces. It is necessary to follow the manufacturer’s installation guidelines, use appropriate tools, and employ precision alignment techniques to ensure optimal performance and longevity of the bearings.

Size and Space Constraints:

In some applications, size and space constraints may limit the use of rolling contact bearings. The available space for bearing installation may be limited, requiring the use of compact or specialized bearing designs. Additionally, certain applications may demand high load-carrying capacity within a restricted envelope, necessitating careful bearing selection and possibly the use of alternative bearing types. It is important to consider the space limitations and select bearings that can accommodate the specified requirements while fitting within the available space.

While rolling contact bearings offer numerous advantages, it is essential to be aware of the potential challenges and limitations associated with their use. By understanding these factors and taking appropriate measures, such as careful selection, proper maintenance, and adherence to installation guidelines, the performance and reliability of rolling contact bearings can be optimized in various industries and applications.

rolling contact bearing

Can you describe the various types of seals and shields used with rolling contact bearings for contamination prevention?

Various types of seals and shields are used with rolling contact bearings to prevent contamination and protect the bearing internals. Here’s a detailed description of the commonly used seals and shields:

Contact Seals:

Contact seals, also known as lip seals or radial seals, are designed to provide a barrier against contaminants while maintaining lubricant retention within the bearing. These seals consist of a flexible lip that makes contact with the inner or outer ring of the bearing. The lip is typically made of synthetic rubber or elastomeric material. Contact seals effectively prevent the entry of solid particles, liquids, and other contaminants into the bearing. They are suitable for applications with moderate operating speeds and rotational requirements where the sealing function takes priority over low friction.

Non-Contact Seals:

Non-contact seals, also known as labyrinth seals or gap seals, create a labyrinthine path that hinders the entry of contaminants into the bearing. These seals do not make physical contact with the bearing rings, resulting in lower friction and reduced heat generation compared to contact seals. Non-contact seals are typically constructed using metallic or non-metallic components with precise geometries to create a tortuous path for contaminants. They are suitable for high-speed applications and environments where low friction and minimal heat generation are important considerations.

Shields:

Shields, also referred to as metal shields or non-contact shields, provide a physical barrier between the rolling elements and the external environment. Shields are typically made of metal, such as steel, and are attached to the outer ring of the bearing. They cover a portion of the bearing’s circumference, leaving a small gap for the rolling elements to function. Shields offer effective protection against larger particles and prevent the direct contact of contaminants with the rolling elements. However, they do not provide a complete seal, allowing for limited air circulation and lubricant flow within the bearing.

Hybrid Seals:

Hybrid seals combine the advantages of contact seals and non-contact seals. These seals use a combination of contacting and non-contacting elements to provide enhanced protection against contamination. Hybrid seals are designed to reduce friction and heat generation while offering improved sealing performance compared to contact seals. They typically incorporate a non-contacting labyrinth or gap seal with additional contact elements, such as lip seals or brush seals, to provide a more effective barrier against contaminants.

Ingress Protection (IP) Ratings:

In addition to the specific seal and shield types, rolling contact bearings may also be assigned Ingress Protection (IP) ratings. IP ratings indicate the level of protection provided against solid particles, such as dust and dirt, as well as liquids, such as water and oil. The IP rating is typically represented by a two-digit number, where the first digit represents the level of protection against solid particles, and the second digit represents the level of protection against liquids. Higher IP ratings indicate greater protection against contaminants.

The selection of the appropriate seal or shield type depends on various factors, including the application requirements, operating conditions, contamination risks, and desired friction characteristics. Manufacturers typically provide information on the recommended sealing options for their bearing products, considering the specific application needs and environmental conditions.

rolling contact bearing

What are the common types of rolling contact bearings, such as ball bearings or roller bearings?

Rolling contact bearings are available in various types, each designed to accommodate specific load capacities, speeds, and application requirements. The most common types of rolling contact bearings include ball bearings and roller bearings. Here’s a detailed explanation of these common types:

Ball Bearings:

Ball bearings are the most widely used type of rolling contact bearings. They consist of one or more rows of balls placed between two rings—an inner ring and an outer ring. The balls roll along the raceways formed on the rings, enabling smooth and low-friction rotation. Ball bearings are known for their high rotational speeds, low starting torque, and relatively low load capacity compared to roller bearings.

There are several variations within the category of ball bearings, including:

Deep Groove Ball Bearings: These ball bearings have deep raceway grooves, allowing them to accommodate both radial and axial loads. They are commonly used in applications such as electric motors, appliances, and automotive components.
Angular Contact Ball Bearings: Angular contact ball bearings can handle both radial and axial loads. They have an angled contact surface between the balls and the raceways, enabling them to support higher axial loads and facilitate combined radial and axial movements. These bearings are often used in machine tools, pumps, and gearboxes.
Thrust Ball Bearings: Thrust ball bearings are designed to support axial loads in a single direction. They consist of two rings with a set of balls sandwiched between them. Thrust ball bearings are commonly used in applications such as automotive transmissions and steering systems.

Roller Bearings:

Roller bearings, as the name implies, utilize cylindrical or tapered rollers instead of balls to facilitate motion. Roller bearings are capable of handling higher loads and are often used in heavy-duty applications. The common types of roller bearings include:

Cylindrical Roller Bearings: Cylindrical roller bearings feature cylindrical rollers that provide a large contact area with the raceways. They can accommodate high radial loads and moderate axial loads. Cylindrical roller bearings are commonly used in applications such as machine tool spindles, electric motors, and gearboxes.
Tapered Roller Bearings: Tapered roller bearings consist of tapered rollers and inner and outer rings with tapered raceways. They can support both radial and axial loads in a single direction. Tapered roller bearings are commonly used in automotive wheel bearings, heavy machinery, and construction equipment.
Spherical Roller Bearings: Spherical roller bearings have barrel-shaped rollers and two raceways on the inner and outer rings that are inclined relative to the bearing axis. This design allows them to accommodate misalignment and axial displacement. Spherical roller bearings are commonly used in applications with heavy loads, such as mining equipment, paper mills, and crushers.
Needle Roller Bearings: Needle roller bearings use long, thin rollers that have a high length-to-diameter ratio. They are suitable for applications with limited radial space and high load capacity. Needle roller bearings are commonly used in automotive transmissions, industrial gearboxes, and motorcycle engines.

These are some of the common types of rolling contact bearings, including ball bearings and roller bearings. Each type has its own advantages and is suitable for specific applications based on factors such as load requirements, speed, and space limitations.

Can you describe the load-carrying capacity and load ratings of rolling contact bearings?

Rolling contact bearings are designed to carry various types of loads in mechanical systems. The load-carrying capacity and load ratings of rolling contact bearings play a crucial role in determining their suitability for specific applications. Here’s a detailed explanation of these concepts:

Load-Carrying Capacity:

The load-carrying capacity of a rolling contact bearing refers to its ability to support and distribute loads without excessive deformation or failure. It is influenced by factors such as the bearing’s design, material properties, and operating conditions. Rolling contact bearings are primarily designed to carry two types of loads:

Radial Loads: Radial loads act perpendicular to the axis of rotation and are supported by the bearing’s raceways. Radial loads can arise from the weight of the shaft, centrifugal forces, or external forces applied to the bearing. The load-carrying capacity for radial loads is typically specified by the maximum radial load the bearing can withstand without suffering permanent deformation or reduced performance.
Axial Loads: Axial loads act parallel to the axis of rotation and are supported by the bearing’s configuration, such as the arrangement of the rolling elements or the presence of thrust surfaces. Axial loads can arise from forces that push or pull along the axis of rotation. The load-carrying capacity for axial loads is typically specified by the maximum axial load the bearing can withstand without experiencing excessive wear or reduced performance.

It’s important to note that the load-carrying capacity of a rolling contact bearing is influenced by factors such as rotational speed, lubrication, temperature, and operating conditions. These factors can affect the performance and durability of the bearing under different load conditions.

Load Ratings:

Load ratings provide standardized values that indicate the maximum permissible loads a rolling contact bearing can carry under specific operating conditions. These ratings help engineers and designers select bearings that can withstand the expected loads in a given application. The two primary load ratings specified for rolling contact bearings are:

Dynamic Load Rating: The dynamic load rating (C) represents the maximum load that a bearing can carry for a specified number of revolutions or operating hours without developing excessive wear or fatigue. It is based on the bearing’s ability to withstand rolling contact fatigue, which is the most common mode of failure in rolling contact bearings. The dynamic load rating is typically provided by the bearing manufacturer and is expressed in units of force (such as Newtons or pounds-force).
Static Load Rating: The static load rating (Co) indicates the maximum load that a bearing can withstand without permanent deformation when the bearing is stationary or subjected to very slow rotational speeds. It represents the load capacity of the bearing under static or slowly changing loads. Similar to the dynamic load rating, the static load rating is also provided by the bearing manufacturer and expressed in units of force.

It’s important to consider both the dynamic and static load ratings when selecting a rolling contact bearing for an application. The dynamic load rating is crucial for assessing the bearing’s ability to withstand the varying loads during operation, while the static load rating provides information about the bearing’s resistance to deformation under stationary or slow-speed conditions.

By considering the load-carrying capacity and load ratings of rolling contact bearings, engineers can choose the appropriate bearing type and size to ensure reliable and efficient operation in their specific applications.

rolling contact bearing

What is the impact of proper lubrication and maintenance on the performance and lifespan of rolling contact bearings?

Proper lubrication and maintenance have a significant impact on the performance and lifespan of rolling contact bearings. Adequate lubrication ensures smooth operation, reduces friction, prevents wear, and extends the service life of the bearings. Here’s a detailed explanation of the impact of proper lubrication and maintenance on rolling contact bearings:

Reduced Friction and Wear:

Proper lubrication forms a thin film of lubricant between the rolling elements and the raceways of the bearing. This lubricating film reduces friction and wear by minimizing direct metal-to-metal contact. It prevents the surfaces from rubbing against each other, reducing frictional forces and minimizing wear on the bearing components. Reduced friction and wear contribute to smoother operation, improved efficiency, and increased bearing lifespan.

Heat Dissipation:

Lubrication in rolling contact bearings helps dissipate heat generated during operation. The lubricant absorbs and carries away heat from the bearing, preventing excessive temperature rise. Adequate heat dissipation is crucial for maintaining proper operating conditions and preventing thermal damage to the bearing components. Proper lubrication ensures efficient heat transfer, which in turn contributes to the overall performance and durability of the bearing.

Protection Against Corrosion and Contamination:

Lubrication acts as a protective barrier, preventing corrosion and contamination of rolling contact bearings. The lubricant creates a barrier that shields the bearing surfaces from moisture, dust, dirt, and other contaminants that can lead to corrosion and premature wear. By providing a protective layer, proper lubrication helps maintain the integrity of the bearing components and extends their lifespan.

Load Distribution:

Proper lubrication ensures effective load distribution within rolling contact bearings. The lubricant helps distribute the applied loads evenly across the rolling elements and the raceways, minimizing stress concentrations and preventing premature fatigue failure. By promoting even load distribution, lubrication enhances the load-carrying capacity and longevity of the bearing.

Prevention of Excessive Clearance:

Over time, rolling contact bearings may experience wear, which can result in increased clearance between the rolling elements and the raceways. Proper lubrication helps reduce this clearance by filling the gaps and providing a cushioning effect. By minimizing excessive clearance, lubrication maintains the proper functioning and performance of the bearing, preventing issues such as vibration, noise, and reduced load-carrying capacity.

Maintenance and Inspection:

Regular maintenance and inspection are essential for optimizing the performance and lifespan of rolling contact bearings. Maintenance activities may include lubricant replenishment, cleaning, and periodic replacement of worn-out bearings. Regular inspections allow for the early detection of any signs of damage, excessive wear, or inadequate lubrication. Timely maintenance and inspections help identify and address potential issues before they escalate, ensuring the continued reliability and longevity of the bearings.

In conclusion, proper lubrication and maintenance significantly impact the performance and lifespan of rolling contact bearings. Adequate lubrication reduces friction, prevents wear, dissipates heat, and protects against corrosion and contamination. It promotes even load distribution and helps maintain the proper functioning of the bearing. Regular maintenance and inspections further ensure optimal performance and allow for timely intervention to address any potential issues. By following proper lubrication practices and conducting regular maintenance, the service life of rolling contact bearings can be extended, leading to improved efficiency, reduced downtime, and cost savings in various applications.

ANGULAR CONTACT BALL BEARING SERIES

where C is 15 degrees contact Angle, AC is 25 degrees contact Angle, B is 40 degrees contact Angle, the bearing limit speed is higher, can bear both radial load and axial load, can also bear pure axial load, the axial load capacity is determined by the contact Angle, and increases with the increase of the contact Angle. It can only withstand the axial load in 1 direction, when bearing the radial load, it will cause additional axial force, and must apply the corresponding reverse load, so the bearing is generally used in pairs.

SINGLE ROW ANGULAR CONTACT BALL BEARING

Single-row angular contact ball bearings can only bear axial load in 1 direction, and additional axial force will be caused when bearing radial load. And only limit the axial displacement of the shaft or housing in 1 direction. Angular contact ball bearings have a contact Angle of 40 degrees, so they can withstand large axial loads. Angular contact ball bearings are of a non-separation design, and the shoulders on both sides of the inner and outer rings are not high or low. In order to increase the load capacity of the bearing, the shoulder on 1 side is machined lower, so that the bearing can fit more steel balls.

DOUBLE ROW ANGULAR CONTACT BALL BEARING

Double row angular contact ball bearings can bear large radial loads, mainly radial and axial combined loads and torque loads, limiting the axial displacement of both sides of the shaft. The inclinability between the inner and outer rings of the double-row angular contact ball bearing is limited in the parts mainly used to limit the two-way axial displacement of the shaft and the housing. The allowable inclination Angle depends on the internal clearance of the bearing, the bearing size, the internal design and the force and moment acting on the bearing, and the allowable inclination Angle should ensure that no excessive additional stress is generated in the bearing. If the inclination Angle between the inner and outer rings of the bearing exists, the life of the bearing will be affected, and the running accuracy of the bearing will be reduced, and the running noise will be increased. Double row angular contact ball bearings generally use nylon cages or brass solid cages. When installing double row angular contact ball bearings, attention should be paid to the fact that although the bearings can withstand two-way axial loads, if there is a ball loading gap on 1 side, care should be taken not to let the main axial load pass through the groove side with a gap. When the bearing is used, attention should be paid to making the raceway without the ball filling gap bear the main load.

bushing

What is the purpose of the bushing?

If you notice the truck making noises when cornering, the bushings may be worn. You may need to replace the ball joint or stabilizer bar, but a simple inspection will reveal that the noise is coming from the bushing. The noise from a worn bushing on a metal joint can mimic the sound of other problems in the suspension, such as a loose stabilizer bar or a failed ball joint.

Function

What is the purpose of the bushing? They play an important role in the operation of various mechanical parts. Their main functions include reducing the clearance between the shaft and the bearing and reducing the leakage of the valve. Bushings are used in different ways to ensure smooth operation and longevity. However, some new designers don’t appreciate the functionality of the case. So let’s discuss these features. Some of their most common applications are listed below.
First, the shell does a lot of things. They reduce noise, control vibration, and provide amazing protection for all kinds of industrial equipment. Large industrial equipment faces more wear, vibration and noise, which can render it completely inoperable. Bushings help prevent this by reducing noise and vibration. Bushing sets also extend equipment life and improve its performance. Therefore, you should not underestimate the importance of the casing in your device.
Another common function of bushings is to support components during assembly. In other words, the bushing reduces the risk of machine wear. In addition to this, they are superior to bearings, which are notoriously expensive to maintain. However, they are still useful, and their versatility cannot be overemphasized. If you’re considering installing one, you’ll be glad you did! These products have become a necessity in the modern industrial world. If you’re wondering how to choose one, here are some of the most common bushing uses.
Electrical bushings are an important part of many electrical equipment. They carry high voltage currents through the enclosure and provide an insulating barrier between live conductors and metal bodies at ground potential. They are made of a central conductive rod (usually copper or aluminum) and surrounding insulators made of composite resin silicone rubber. Additionally, the bushings are made of various materials. Whether copper, aluminum or plastic, they are an important part of many types of electrical equipment.

type

There are several different types of bushings on the market today. They may be cheap but they are of good quality. These products can be used in telephones, cable television, computer data lines and alarm systems. The key to buying these products online is finding the right appliance store and choosing a high-quality product. An online appliance store should have comprehensive information and ease of use. For the right electrical bushing, you should look for reliable online stores with the best prices and high quality products.
Capacitive grading bushings use conductive foils inserted into paper to stabilize the electric field and balance the internal energy of the bushing. The conductive foil acts as a capacitive element, connecting the high voltage conductor to ground. These types of bushings are sometimes referred to as capacitor grade bushings. Capacitive grading bushings are usually made of paper impregnated with epoxy resin or mineral oil.
When buying enclosures, you should know how they are used. Unlike ball bearings, bushings should be stored upright so that they are in the correct working position. This is because horizontal placement can cause air bubbles to form in the fill insulation. It is also important to store the bushing properly to prevent damage. The wrong way to store these components can result in costly repairs.
In addition to the physical structure, the bushing insulation must also be effective over the long term. It must resist partial discharge and working electric field stress. The material and design of the bushing can vary widely. Early on, porcelain-based materials were popular in bushing designs. Porcelain was chosen because of its low cost of production and very low linear expansion. Ceramic bushings, on the other hand, require a lot of metal fittings and flexible seals.

Durability

The RIG 3 Bushing Durability Test Standard simulates real-world service conditions for automotive bushings. This three-channel test standard varies casing loads and stresses by applying a range of different load conditions and various control factors. This test is critical to the durability of the case, as it accurately reproduces the dynamic loads that occur during normal use. This test is a key component of the automotive industry and is widely used in many industries.
The Advanced Casing Model has five modules to address asymmetry, nonlinearity, and hysteresis. This model also represents the CZPT lag model. The model can be parameterized in the time domain using MATLAB, and the results can be exported to other simulation software. The developed bushing model is a key component in the durability and performance of vehicle suspension components.
A conductive material is coated on the inner surface of the sleeve. The coating is chosen to conduct a certain amount of current. The conductive path extends from the blade spacer 126 to the sleeve projecting edge 204 and then through the housing 62 to the ground. The coating is made of a low friction material and acts as a wear surface against the bushing sidewall 212 and the housing 62 .
Another important factor in a bushing’s durability is its ability to friction. The higher the operating speed, the greater the load on the bushing. Since bushings are designed for lighter loads and slower speeds, they cannot handle large loads at high speeds. The P-max or V-max value of a bushing is its maximum load or speed at 0 rpm. The PV value must be lower than the manufacturer’s PV value.

price

If you need to replace the bushing on the control arm, you should understand the cost involved. This repair can be expensive, depending on the make and model of your car. Generally, you should pay between $105 and $180 for a replacement. However, you can choose to have it done by a mechanic at a lower cost. The labor cost for this job can be around $160, depending on your automaker.
The cost of replacing the control arm bushings can range from $200 on the low end to $500 on a luxury car. While parts are cheap, labor costs are the highest. Mechanics had to remove suspension and wheel assemblies to replace bushings. If you have some mechanical knowledge, you can replace the bushing yourself. Control arm bushings on the wheel side are usually about $20 each. Still, if you’re not a mechanic, you can save money by doing it yourself.
bushing

Install

Press-fit bushings are installed using a retaining ring with a diameter 0.3/0.4 mm larger than the inner diameter of the bushing. To ensure accurate installation, use a mechanically driven, pneumatic or hydraulic drill and insert the bushing into the appropriate hole. This process is best done using mounting holes with drilled holes for the clamps. Make sure the mounting hole is in the center of the bushing and free of debris.
Once the bushing is positioned, use a vise to install its nut. A cold bushing will compress and fit the shell better. Place the sleeve in the refrigerator for at least 24 hours to aid installation. After removing the bushing from the refrigerator, make sure it has enough diameter to fit into the enclosure. Next, place the opposite socket into the enclosure and use it as a stand. After a few minutes, the bushing should be fully seated in the housing.
Install the new bushing into the housing hole. If the previous one had a metal case, insert the new one through the taper. Always lubricate the inner and outer surfaces of the bushing. Then, apply pressure to the inner metal sleeve of the new bushing. You may notice that the new bushing does not exactly match the housing hole. However, that’s okay because the outer diameter of the bushing is larger than the outer diameter of the hub drive.
The installation of the bushing requires the use of the hydraulic unit 16 . Hydraulic unit 16 is located near the #1 journal of the camshaft and extends from #2 to #7. Hydraulic fluid forces piston 22 away from the outer end of cylinder 20 and pushes shaft 14 forward. The shaft is then moved forward, pushing the bushing 17 onto the piston. Multiple bushings can be installed in a single engine.
