Bearing is a machine element that have constrained relative motions and used to reduces friction between moving 90x190x43 Bearing parts of machine to obtain desired motion or we can say that the machine elements which are support the rotating parts of a machine and reduce friction are called bearings.

Radial Ball Bearings are generally the most popular high precision bearing type used in industrial applications NSK ps2 Bearing because of their versatility. They are usually chosen over Angular Contact Bearings when: Support is needed for axial loads that move in both directions; Bearing space is limited.
