What is a rolling bearing

Rolling bearings are precision components widely used in mechanical equipment. Their main function is to reduce friction between moving parts and support rotational or linear motion loads. Rolling bearings achieve efficient energy transfer by rolling elements (such as balls, cylinders or cones) between inner and outer rings and are an indispensable key component in modern industry.

Structure and classification of rolling bearings

Rolling bearings usually consist of the following main parts:

Depending on the shape and arrangement of the rolling elements, rolling bearings can be divided into the following categories:
