NACHI 5304ZZ 5300 Angular Contact Ball Bearing, 20 mm Dia Bore, 52 mm OD, 2 Rows, 22.2 mm W, 20 deg, 21700 N Dynamic/13300 N Static Load
A double-row angular contact ball bearing is basically two single-row angular contact ball bearings with 20 deg contact angles, mounted back-to-back while contained within a narrower single bearing. These bearings occupy less axial space and can take a bi-directional axial, radial and moment loads in one bearing where it takes a matched pair otherwise.

NACHI 7212B Angular Contact Ball Bearing, 60 mm Dia Bore, 110 mm OD, 1 Row, 22 mm W, 40 deg, 58000 N Dynamic/46000 N Static Load
The single-row angular contact ball bearing was designed to support radial, axial or composite loads, however, the axial load must be in one direction. The high thrust capacity is achieved by a higher shoulder on one side of the outer ring. A matching high shoulder is often on the opposite side of the inner ring as well. The direction of the load through the balls forms the contact angle. The thrust capacity increases with the contact angle. This ball bearing has a 40 deg contact angle. This bearing has a stamped steel cage and is not available with seals or shields. These bearings are non-separable. These bearings have normal tolerances and are not suitable for mounting adjacent to each other to achieve a preload.
