53000U Series thrust ball bearings

53000 U-bearings are equipped with self-aligning seat washers to compensate for angular misalignment between the shaft and the housing support surface. Spherical seat washers are marked with basic designations U2, U3, or U4 plus two digits for size — for example, U320 for bearing 53320.
