Bearings are modern machinery and equipment is an important component. Its main function is to support the mechanical rotating body, 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 has been standardized, serialized, but compared with the sliding bearing its radial dimension, vibration and noise are large, the price is higher.

Rolling generally consists of an outer ring, inner ring, rolling elements and cage four parts, strictly speaking, by the outer ring, the inner ring, rolling elements, cage, seals, lubricants six pieces of composition. Mainly includes outer, inner ring, rolling elements can be given meaning-bearing. According to the shape of the rolling elements, bearing into ball bearings and roller bearings two categories.

A bearing is a mechanical element which is used to support another moving element.

It is used to give free rotational motion to the shaft. It reduces the friction and heat.

Bearings should have following properties-
