The 51105 thrust ball bearing is designed to support axial loads in one direction while operating at relatively low to medium speeds. It consists of a shaft washer, housing washer, and a ball and cage assembly, providing smooth axial force transmission with low friction.
This bearing is widely used in automotive systems, machine tools, industrial equipment, and vertical shaft applications where axial positioning and load stability are required.
