Bearings are an important part of contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and to ensure its rotation accuracy.
According to the different friction properties of sports components, bearings can be divided into two categories of rolling bearings and plain bearings. Rolling bearings have been standardized, serialized, but compared with the sliding bearing its radial size, vibration and noise, the price is higher.
Rolling bearings generally by the outer ring, inner ring, rolling body and cage composed of four parts, strictly speaking, by the outer ring, inner ring, rolling body, cage, sealed, composed of six pieces of lubricants. Simply put, as long as the outer ring, inner ring, rolling body can be defined as rolling bearings. According to the shape of the rolling body, rolling bearings are divided into ball bearings and roller bearings two categories
