Angular Contact Ball Bearings Industry knowledge

What are the radial and axial load capacities of angular contact ball bearings? How do they affect bearing selection and application?

The load capacity of angular contact ball bearings refers to the maximum radial and axial loads they can withstand. These capacities depend on the size, design, and material of the bearing. Angular contact ball bearings are usually designed to withstand both radial and axial loads, but they are usually more capable of withstanding axial loads.
Radial load: The ball between the inner and outer rings of the bearing can withstand radial loads, but the magnitude of this load is limited by the size and design of the bearing. The radial load capacity is usually expressed by the basic load rating (C) of the bearing.
Axial load: The contact angle of angular contact ball bearings is designed to allow them to withstand high axial loads. The larger the contact angle, the greater the bearing's ability to withstand axial loads. The axial load capacity is usually expressed by the basic load rating (Ca) of the bearing.
Bearing selection and application should consider the type and magnitude of loads under actual operating conditions to ensure that the bearing can operate safely and have adequate life.

How do the contact angles of different angular contact ball bearings differ? How does the contact angle affect the load distribution and application of the bearing?

The contact angle is a key parameter in the design of angular contact ball bearings, which affects the load distribution and application of the bearing. The contact angle refers to the angle between the tangent line and the radial plane at the contact point between the ball and the inner and outer rings.
Differences in contact angles: The contact angle of angular contact ball bearings is usually between 15° and 40°, and bearings with different contact angles are suitable for different load conditions. For example, bearings with a 15° contact angle are more suitable for bearing larger axial loads, while bearings with a 25° contact angle provide a better balance between radial and axial loads.
Effect of contact angle: The size of the contact angle directly affects the load distribution of the bearing. A larger contact angle can improve the bearing's ability to withstand axial loads, while a smaller contact angle helps improve the bearing's radial load capacity. Choosing the right contact angle is critical to ensuring the performance of the bearing in a specific application.

What are the accuracy grades of angular contact ball bearings? How does the accuracy grade affect the performance and life of the bearing?

The accuracy grade of angular contact ball bearings is defined according to international standards (such as ISO), which affects the dimensional accuracy, shape accuracy and rotation accuracy of the bearing. The higher the accuracy grade, the better the performance and life of the bearing, but the higher the cost.
Accuracy grade classification: Common accuracy grades include P0 (normal accuracy), P6, P5, P4 and P2, etc. P0 is the most basic accuracy grade, suitable for general applications; while high-precision grades such as P6, P5, P4 and P2 are suitable for applications with higher precision requirements, such as precision machine tools, high-speed rotating equipment, etc.
Impact of accuracy grade: Bearings with higher accuracy grades have stricter dimensional tolerances, shape tolerances and surface roughness requirements, which help reduce bearing friction, improve rotation accuracy, reduce noise and extend bearing life. However, the cost of high-precision bearings is also relatively high, so when selecting bearings, it is necessary to weigh the specific requirements of the application and cost-effectiveness.
