Product Overview: The 51428 Thrust Ball Bearing
The 51428 Thrust Ball Bearing is a high-capacity component specifically engineered to manage heavy axial loads in a single direction. As a key part of our 51400 Series, this bearing is designed with precision-grooved raceways in both the shaft and housing washers to support purely axial forces. With its principal dimensions of 140mm Bore Diameter, 250mm Outer Diameter, and 85mm Thickness, it is built for robust performance in demanding industrial environments. The separable design, consisting of a shaft washer, a housing washer, and a ball and cage assembly, allows for straightforward mounting and dismounting, simplifying maintenance procedures. This bearing is an essential component for applications requiring high axial stiffness and precise rotational control under heavy thrust loads.
