Andrews Thrust Ball Bearings Guide
Product Description
The Andrews W4–1/2 Thrust Ball Bearing features a medium cross-section, single-direction design consisting of two grooved thrust washers and a ball-and-cage assembly. Its grooved raceways support smooth rotation and stable axial load distribution, providing reliable thrust support in mechanical assemblies. Designed to accommodate axial loads in one direction, the bearing is suitable for industrial pumps, machine tools, and mechanical drive systems, with speed limits specified for oil lubrication. HSN provides replacement bearing solutions for U.S. equipment maintenance, aftermarket sourcing, and OEM applications, with dimensional verification and custom supply options available.
