Backing Bearings for Multi-Roll Rolling Cluster Mills - (Replace NSK)

Back-Up Roll Bearings for Sendzimir Mills The bearings for this application have very thick outer rings compared with ordinary bearings because the bearing periphery serves as the back-up ro. Since these bearings must maintain high precision under heavy load, they are designed to have the maximum oad capacity. The types available are cylindrical roller bearings, tapered roller bearings, spherical roller bearings, and needle roller bearings, with cylindrical roller bearings being most popular. Since 3PL type cylindrical roller bearings and needle roller bearings cannot sustain axial loads, plastic thrust rings are used for the axial loads. Several back-up roll bearings are mounted on one shaft and their outer ring peripheries serve as the back-up roll. Therefore, the outer ring radial runout and thickness variation after mounting are strictly controlled. lf the outer ring peripheries become rough, the bearings can be reused by regrinding the surface.
