Product Decription
Angular contact ball bearings mainly bear a large unidirectional axial load, the greater the contact Angle, the greater the load bearing capacity. The cage material is steel plate, brass or engineering plastic, and the forming method is stamping or turning, depending on the bearing form or use conditions. Others include combination angular contact ball bearings, double row angular contact ball bearings and four-point contact ball bearings.
Angular contact ball bearings can bear both radial and axial loads. Can work at higher rotational speeds. The larger the contact Angle, the higher the axial carrying capacity. High precision and high speed bearings usually take a 15 degree contact Angle. Under axial force, the contact Angle will increase. 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. If it is installed in pairs, the outer rings of a pair of bearings are relative, that is, the wide end faces the wide end face and the narrow end faces the narrow end face. This avoids causing additional axial forces and allows the shaft or housing to be confined to axial clearance in both directions.

Can you Explain the Design and Construction of Tapered Roller Bearings?
The design and construction of tapered roller bearings are characterized by their conical geometry and specific components that enable them to handle radial and axial loads simultaneously. Here’s an overview of their design and construction:
- Components:
Tapered roller bearings consist of the following components:
- Inner Ring:
The inner ring has a conical raceway on its inner surface, which matches the conical shape of the rollers. It serves as the raceway for the rollers and provides support to the rotating assembly.
- Outer Ring:
The outer ring also features a conical raceway on its inner surface that complements the shape of the rollers. The outer ring provides a rigid structure to house the entire bearing assembly.
- Tapered Rollers:
The rollers have a conical shape with varying diameters along their length. This design allows the rollers to make point contact with the inner and outer raceways, distributing loads efficiently.
- Cage:
The cage or retainer holds the rollers in position, maintaining proper spacing and preventing them from coming into contact with each other. The cage material can vary, and its design may affect factors like friction and heat generation.
- Conical Geometry:
The distinguishing feature of tapered roller bearings is their conical geometry. The conical angle is defined by the contact angle between the roller axis and the bearing axis. This angle facilitates effective load distribution and axial load support.
- Load Distribution:
The conical shape of the rollers and raceways allows tapered roller bearings to handle both radial and axial loads. Radial loads are primarily supported by the larger diameter of the rollers at the large end of the cone, while axial loads are absorbed by the smaller diameter near the small end of the cone.
- Adjustable Clearance and Preload:
Many tapered roller bearings allow for adjustable internal clearance or preload. This feature enables fine-tuning of the bearing’s internal play, optimizing performance and minimizing friction.
- Thrust Capability:
Tapered roller bearings can handle thrust (axial) loads in one direction, making them suitable for applications where axial loads need to be managed along with radial loads.
- Applications:
Tapered roller bearings find applications in various industries, including automotive, heavy machinery, aerospace, and more. They are used in scenarios that require efficient load distribution and handling of combined loads.
In summary, tapered roller bearings are designed with conical geometry to accommodate both radial and axial loads. Their specific components, such as tapered rollers and a cage, work together to ensure effective load distribution, making them suitable for a wide range of industrial applications.
