Thrust Ball Bearing/Product Information/Koyo Bearings (JTEK

This page introduces thrust ball bearings. There are single-direction and double-direction thrust ball bearings and the former can withstand axial load in a single direction, while the latter can withstand load from both directions. Here you will find related catalogs, links to technical calculation tools and CAD drawings useful

Ball & Roller Bearin

(DF) a. *Carries radial load and axial load in both directions. *Has a smaller moment load accommodating capacity than the back-to-back arrangement, because the distance between the load centers (a) is shorter. *As for the preloaded type, the clearance is pre-adjusted so that bearings will be preloaded the proper amount
