Single row angular contact ball bearings
RKB single row angular contact ball bearings can take axial loads in just one direction. This type of bearing is normally paired in face-to-face (DF) or back-to-back (DB) configuration, depending on load conditions, presence of tilting moments and misalignment magnitude in the application.
