51320 Thrust Ball Bearing | Single Direction Axial Load

The 51320 is a thrust ball bearing from the 513 series, designed with a 100 mm bore diameter to support axial loads in a single direction. Thrust ball bearings use ball rolling elements between hardened raceways to accommodate high thrust loads at moderate speeds.

Typical applications include machine tool spindles, automotive transmissions, crane hooks, and vertical pump assemblies where space is limited and axial forces must be managed efficiently. These bearings are commonly used in conjunction with radial bearings to handle combined loads.
