FAG Rolling Bearings in Rolling Mills - Schaeffler

Roller bearings have a higher load carrying capacity than ball bearings. As a result, the radial forces are supported by roller bearings only, namely cylindrical roller bearings, tapered roller bearings or spherical roller bearings. The material used for the bearing rings and rolling elements is through hardening rolling bearing steel or, in some cases,

Bearings for Rolling mill Rolls – IspatGuru

17/05/2017  Axial bearings such as axial tapered roller bearings, double-row tapered roller bearings, and axial spherical roller bearings are mostly used in the heavy mills, where considerable axial forces occur in combination with low to moderate speeds. During operation, only one bearing row is subjected to pure axial load. The other is not subjected to load. In order to prevent distorted rolling kinematics, the outer rings of the double-row tapered roller bearings

NSK KV type, four roll tapered roller bearings and in some mills, NSK KH type, two roll tapered roller bearings are used. Special heavy duty roller retainer designs are used because of the high axial forces and misalignment. Low radial internal clearance insures that there is even load distribution across the bearing. Loose fits are used on both the inner and outer rings. Cylindrical Roller ...
