Backing bearings are particularly thick outer ring of the rolling bearing, when used to form a group to be mounted on the shaft of a stationary support rollers. Pressure on the work roll through the intermediate roller and the support roller is passed to the system to the rack through the saddle. Generally used for multi-roll cold rolling mill equipment can also be used for other occasions, such as straightening machine.

Thrust bearing assembly primarily axial load, and its application
Bearing installation method, under normal circumstances the majority of the shaft rotates, so the inner ring and shaft with an exaggeration win cooperation,
Tapered bearing outer ring and bearing chamber fit for the clearance fit. Thrust bearing assembly primarily axial load, and its application
Extensive. Although the thrust bearing installation operation is relatively simple, but the actual repair is still often errors occur, namely the bearing ring and loosen tight
Ring mounting location is incorrect, the results of the bearing out of action, the journal will soon be worn. Tight inner ring and the journal for the transition fit
When the shaft rotates driven tight ring, and with the stationary element face friction, subjected to axial force (Fx), the friction will occur
Torque is greater than the inside diameter with resistance torque, resulting in tight ring and the shaft with face mandatory rotation, exacerbated journal wear.Thrust ball bearings can withstand high speed thrust load design, the ball rolling with a rolling groove of the washer-like ring structure
Percent. Because saddle-shaped rings, therefore, thrust ball bearings are divided into flat seat type and tone spherical thrust ball bearings hheey
Seat model types. In addition, the bearings can withstand axial load, but can not bear radial load. Comprehensive and bearing force
Shaft with generally transition fit, seat ring and the bearing housing bore with the generally loose fit, so this bearing easier installation
Spring thrust bearing should the shaft axis fixed relative to the axis of rotation in order to prevent
