Bearing (Bearing) is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient (friction coefficient) during its movement, and ensure its rotation accuracy (accuracy).

According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial size, vibration and noise are larger, and the price is higher.

Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling element and cage. Strictly speaking, it is composed of six parts: outer ring, inner ring, rolling element, cage, seal and lubricating oil. Simply put, as long as the outer ring, inner ring, rolling element can be defined as a rolling bearing. According to the shape of the rolling body, rolling bearings are divided into two categories: ball bearings and roller bearings.
