51114-Thrust ball bearing-FGFA bearings

51114 Single direction thrust ball bearing

Thrust ball bearings are primarily designed to withstand axial loads, engineered to handle thrust forces during high-speed operation. They are incapable of bearing radial loads and have a relatively low maximum rotational speed. Offering straightforward installation and maintenance, they find extensive application in machinery such as machine tools, electric motors, cranes, and automotive gearboxes.
