Thrust Ball Bearings are designed to withstand thrust loads during high-speed operation, and consist of washer-like ferrules with raceway grooves for ball rolling. Since the ferrule is in the form of a seat cushion, the thrust ball bearing is divided into two types: flat seat cushion type and self-aligning spherical seat cushion type. In addition, this bearing can withstand axial loads, but not radial loads. Thrust ball bearing composition: Thrust ball bearing consists of three parts: seat washer, shaft washer and steel ball cage assembly. The shaft washer matched with the shaft and the seat ring matched with the housing.
