When installing a single direction thrust ball bearings, check the verticality of the shaft ring and the centerline of the shaft. The method is to fix the dial gauge to the end surface of the casing, so that the contact of the watch top rotates the bearing on the bearing shaft raceway, and observes the dial gauge pointer.Single Direction Thrust Ball Bearing KML Bearing USA’s Single Direction Thrust Ball Bearings are designed for axial loads in one direction only at primarily a 90° contact angle. Commonly, used to reduce noise and provide smooth motion for vertical shafts in automotive, marine and aerospace applications.

Single direction thrust ball bearing can withstand single axial load while double direction thrust ball bearing can withstand bi-direction axial load. The ring should match with shaft for bi-direction thrust ball bearing. The bearing with seat ring in spherical mounting surface has the capacity of self-aligning.Angular contact ball bearings .
