bearing into ball bearings

Bearings are modern machinery and equipment is an important component. Its main function is to support the mechanical rotating body,crossed roller bearing reducing its coefficient of friction during movement, and to ensure the accuracy of its rotation.
According to the different nature of friction of moving parts, bearings Rolling and plain bearings can be divided into two categories. Wherein Rolling been standardized, serialized, but compared with the sliding bearing its radial dimension, vibration and noise is large, the price is higher.
Rolling generally consists of an outer ring, inner ring, rolling elements and cage four parts. According to the shape of the rolling elements, bearing into ball bearings and roller bearings two categories.
