Differentiation of bearing categories


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

According to the load direction or nominal contact angle, bearings are divided into: radial bearings and thrust bearings.

According to the type of rolling element, they are divided into: ball bearings and roller bearings.

According to whether they can be centered, they are divided into: aligning bearings and non-aligning bearings (rigid bearings).

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

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

In addition, there are classifications based on structural shape and size.
