Engineers, maintenance technicians, and DIY builders working on motors, gearboxes, pumps, and machine tool spindles need a thrust bearing that holds its geometry under sustained one-directional axial loads — without constant replacement.\u003c\/p\u003e\n\u003cp\u003eThese thrust ball bearings are three-part assemblies consisting of a shaft washer, a housing washer, and a ball-and-cage assembly. Manufactured to standard 511xx and 512xx series dimensions, they cover inner diameters from 10 mm (0.39 in) to 120 mm (4.72 in), outer diameters from 24 mm (0.94 in) to 155 mm (6.10 in), and heights from 9 mm (0.35 in) to 25 mm (0.98 in).
