3.The method of bearing installation:
(1) cleaning bearings and related components;
(2) check the connected components of size and finishing machining;
(3) installation
(4) inspection of the bearings after installed;
(5) the supply of lubricant.
 
4.Working principle :
Deep groove ball bearings mainly take radial load as well as both radial and axial load. When only radial load, the contact angle is zero. When deep groove ball bearings with radial clearance with the performance of angular contact bearings, can withstand large axial load, deep groove ball bearings, the friction coefficient is small, the speed is also high.
