Thrust ball bearing, also known as TBB bearing, is one of the rotary ball bearings. It owns the same features of other ball bearings, i.e. permitting rotation among the parts. Thrust ball bearing is composed of housing ring, shaft ring, cage, and balls. ZWA Bearings, a China thrust ball bearing factory, manufactures China Thrust Ball Bearing (TBB bearings ) for different applications, especially in steel making, mining, and cement industry. The ring that matches with the shaft is called the shaft ring and the one that matches with the housing is called the housing ring. Those parts are separable and assembled on the shaft while in application. This kind of bearing can only bear axial load not subjected to any radial load. If in high-speed application, oil lubrication is a must.
