Thrust ball bearing with cover, as the name suggests, is to add a metal outer cover outside the general unidirectional thrust ball bearing to cover the outer diameter surface of the bearing's housing washer, which plays a role of isolation and protection. The inside of the bearing is lubricated with grease, which can be used for a long time without maintenance. In addition, our company also produces a special thrust ball bearing with protective cover for automobile suspension, which is maintenance-free for life.
