Ball Angular Contact (AB)

Angular contact ball thrust bearings are designed to accommodate both radial and thrust loads with their large thrust carrying capacity being the primary design feature. These bearings are inch series and typically have an angle of contact around 50 degrees. Angular contact ball thrust bearings consist of hardened and ground angular contact plates with dowel pin holes for mounting and a brass cage with precision balls. The single ball path AB series can handle thrust load in one direction only. Largely used at the bottom of vertical shaft applications, this design accommodates large thrust loads while providing center alignment for the shaft. Specific applications are indexing tables and oilfield rotary table bearings.
