What are the classifications of bearings?


Bearings are important components in mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission process of the equipment.

Bearings are divided into radial bearings and thrust bearings according to the bearing direction or the nominal contact angle.

According to the type of rolling element, it is divided into: ball bearing, roller bearing.

According to whether it is self-aligning, it is divided into: self-aligning bearings, non-aligning bearings (rigid bearings).

According to the number of rows of rolling elements, it is divided into: single-row bearings, double-row bearings, and multi-row bearings.

According to whether the parts can be separated, they are divided into: separable bearings and non-separable bearings.

In addition, there are classifications by structure shape and size.
