Single row angular contact ball bearings

SKF single row angular contact ball bearings (fig. 1) can accommodate axial loads in one direction only. A single row bearing is typically adjusted against a second bearing.
The bearings are non-separable and the bearing rings have one high and one low shoulder. The low shoulder enables a large number of balls to be incorporated in the bearing, giving it a relatively high load carrying capacity.
The standard assortment of SKF single row angular contact ball bearings comprises bearings in the 72 B(E) and 73 B(E) series. Some sizes in the 70 B series are also available. Sealed bearings are avialable with bore diamaters ranging from 15 to 55 mm in the 72 B(E) series and from 12 to 50 mm in the 73 B(E) series.
SKF inch bearings in the ALS and AMS series are mainly used in the aftermarket and, therefore, SKF recommends not to use these bearings for new bearing arrangement designs.
Some large size bearings are available with a flanged outer ring.
In addition, SKF single row angular contact ball bearings are available in many other designs, dimension series, and sizes.
Some SKF single row angular contact ball bearings can be supplied with one locating slot in the outer ring (designation suffix N1).
