Angular Contact Thrust Ball Bearings - Designs and Variants
Single Direction Angular Contact Thrust Ball Bearings
Single direction angular contact thrust ball bearings are designed to accommodate axial loads in one direction only. They are adjusted against a second bearing or mounted as sets, ensuring optimal load distribution. In their primary application, such as rotary tables, two bearings are always used and adjusted against each other for maximum performance.
Double Direction Angular Contact Thrust Ball Bearings
Double direction angular contact thrust ball bearings consist of one housing washer, two shaft washers, and two different-sized ball and cage assemblies. The larger bearing half offers a higher load-carrying capacity. These bearings can handle axial loads in both directions and moment loads, making them ideal for supporting rotating machine components relative to stationary parts.
