51312 Thrust Ball Bearing | Single Direction Axial Load

The 51312 is a thrust ball bearing from the 513 series, designed with a 60 mm bore diameter to support axial loads in a single direction. Thrust ball bearings use ball rolling elements between hardened raceways to accommodate pure thrust loads with minimal friction.

Typical applications include vertical pump shafts, machine tool spindles, automotive transmissions, and crane hooks where predominantly axial forces must be supported. These bearings require proper mounting on flat, rigid surfaces and are commonly used in combination with radial bearings to handle combined loads.
