Advantages of rolling bearings.

Although there are many types and varieties of rolling bearings, they have their own fixed characteristics. However, they have the following common advantages compared with sliding bearing:

(1) small starting friction coefficient and less friction coefficient.

(2) international standards and specifications are unified, and products with interchangeability are readily available.

(3) convenient lubrication and low consumption of lubricant.

(4) in general, a set of bearings can bear both radial and axial loads at the same time.

(5) it can be used conveniently in high temperature or low temperature.

(6) the bearing rigidity can be improved by applying prepressure.
