51102 Thrust Ball Bearings

The 51102 is a thrust ball bearing from the 511 series with a 15 mm bore diameter. Thrust ball bearings are designed to support axial loads in one direction and provide precise axial guidance with minimal friction in rotating assemblies.

These bearings are commonly used in machine tool spindles, automotive transmissions, marine propulsion systems, and industrial gearboxes where space is limited and purely axial loads must be accommodated. They are typically combined with radial bearings in applications requiring both axial and radial load support.
