51318
The 51318 is a thrust ball bearing from the 513 series with a 90 mm bore diameter. Thrust ball bearings are designed to accommodate axial loads in a single direction and provide precise axial guidance for rotating assemblies.
These bearings are commonly used in machine tool spindles, automotive transmissions, marine propulsion systems, and vertical pump applications where high axial load capacity and accurate positioning are required. They must be used in combination with radial support bearings to handle combined loads.
