Usage and Applications

These steels are used for ball and roller bearing applications and are comprised of low carbon steels and high carbon through harden able steel.

First the famous 1C-1.5Cr steel from which the majority of bearings are made. Its structure is apparently well-understood and the focus is on purity in order to avoid inclusions which initiate fatigue during rolling contact. Then there is the M50 steel and its variants, from which bearings which serve at slightly higher temperatures in aeroengines are manufactured, based on secondary-hardened marten site.

Tapered roller bearing are generally used to support combined load mainly consisting of radial load. Their cups are separable for easy assembling ,During mounting and using, radial clearance and axial clearance can be adjusted and preloaded mounting can be made.
