51215

The 51215 is a thrust ball bearing with a 75 mm bore diameter from the 512 series. Thrust ball bearings are designed to support axial loads in one direction and provide precise axial positioning of rotating components.

These bearings are commonly used in automotive transmissions, machine tool spindles, vertical pump assemblies, and crane hooks where space-efficient axial load capacity is required. The single-direction design makes them suitable for applications with predominantly thrust loads and minimal radial loading.
