Thrust Ball Bearings

Bearing Overview

Thrust ball bearings are designed to support axial loads only and are suitable for low-speed applications where axial positioning is required. They consist of a shaft washer, a housing washer, and a ball-and-cage assembly. Available in single-direction and double-direction types, they are commonly used in machine tool spindles, automotive applications, and vertical shafts. Our thrust bearings deliver smooth rotation, precise alignment, and long service life under axial loads.
