What are rolling bearing types?

Rolling bearing types are mainly classified into radial bearings and thrust bearings. Common types include deep groove ball bearings, self-aligning ball bearings, and cylindrical roller bearings.

1. Classification by load direction: Rolling bearing types include:
* Radial bearings: Primarily used to bear radial loads, with a nominal contact angle of 0°≤a≤45°.
* Thrust bearings: Primarily used to bear axial loads, with a nominal contact angle of 45°<a≤90°.

2. Common rolling bearing types:
* Deep groove ball bearings: The most common type of rolling bearing, capable of bearing radial and bidirectional axial loads. Suitable for high-speed applications, with low friction and low noise.
* Self-aligning ball bearings: Have an automatic self-aligning function, compensating for deviations caused by installation errors or shaft deflection. Suitable for heavy-load and impact load applications.
* Cylindrical roller bearings: Suitable for bearing large radial loads, with a low coefficient of friction, suitable for high-speed applications.
* Angular contact ball bearings: Capable of bearing radial and unidirectional axial loads. The larger the contact angle, the stronger the axial load capacity. Suitable for applications requiring large axial loads.

Thrust ball bearings: Specifically designed to withstand axial loads, suitable for low-speed, heavy-load applications.

3. Other types: Thrust roller bearings, needle roller bearings, etc., are suitable for specific applications and have their own advantages, disadvantages, and applicable conditions.

The selection of rolling bearing types should be determined based on specific application requirements, load type, and working environment to ensure the normal operation and service life of the equipment.
