Angular contact ball bearings

The raceways of the inner and outer rings of this type of bearing are made with a set contact angle.
These bearings are not separable. Since the balls are inserted using a counter-drilling construction, a greater number of balls can be installed than in the case of rigid ball bearings.
Standard cage materials can be pressed steel, high-strength brass, or polyamide. Cage materials depend on the bearing series and/or service conditions. Single-row angular contact ball bearings can support radial, axial, or combined loads, however, any axial load must be in one direction. This type of bearing is generally used in pairs to handle the induced load resulting from the internal axial force generated by the applied radial load. When mounting two individual bearings in adjacent positions, NACHI provides these combined parts (pairs) with pre-adjusted clearance. Paired combined bearings are paired assemblies. Combined or paired bearings can be arranged back-to-back (DB), face-to-face, or in tandem (DT). DB or DF assemblies can support bidirectional axial loads.
