Double Direction Thrust Ball Bearing 52215 Metric 65x115x65mm for Machine Tool Spindles

Double Direction Thrust Ball Bearing 52215 Metric 65x115x65mm for Machine Tool Spindles and Crane Hooks

The 52215 Double Direction Thrust Ball Bearing is designed to accommodate heavy axial loads in both directions while maintaining precise axial shaft positioning. Featuring a separable construction with one central shaft washer, two housing washers, and two ball-and-cage assemblies, it is widely used in machine tool spindles, heavy crane hooks, and industrial gearboxes where bi-directional axial thrust support is strictly required.
