BEARINGS A bearing is machine part, which support a moving element and confines its motion. The supporting member is usually designated as bearing and the supporting member may be journal. Since there is a relative motion between the bearing and the moving element, a certain amount of power must be absorbed in overcoming friction, and if the surface actually touches, there will be a rapid wear. Classification: Bearings are classified as follows: Depending upon the nature of contact between the working surfaces:- __Sliding contact bearings and __Rolling contact bearings. SLIDING BEARINGS: Hydrodynamically lubricated bearings Bearings with boundary lubrication Bearings with Extreme boundary lubrication. Bearings with Hydrostatic lubrication. Rolling element bearings: 1,Ball bearings 2,Roller bearings 3,Needle roller bearings Based on the nature of the load supported: • Radial bearings - Journal bearings • Thrust bearings ...
