7211AC P4 Angular Contact Ball Bearing 55*100*21mm SUNBEARING

Product Description

7211C Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis, which means that they are designed to accommodate combined loads, i.e. simultaneously supporting radial and axial loads. The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.Retainers are made of brass, synthetic resin of others subject to individual bearing features and application conditions.

Application

Angular contact ball bearings are mainly used for steel industry, mining&construction, paper making machinery, wind turbines, semiconductors, machine tools, gearboxes, electric motors, pumps&compressors, injection molding machines.
