Double-row angular-contact ball bearing corresponds in its construction to a pair of angular-contact single-row ball bearings in the open arrangement ('O'). We can set part several makings of guided tracks of these bearings conformably to their contact angles:
· 25° - B designation behind the bearing's symbol
· 32° - no designation behind the bearing's symbol
· 35° - no designation behind the bearing's symbol
· 45° - D or DA designation behind the bearing's symbol (detached internal ring).

There are types with a steel cage, brazen cage and a cage made from polyamide in sealed 2RS as well as ZZ variants.

The bearing can accommodate heavy radial loads and axial loads in both directions. It is especially suitable for bearing mountings from which rigid guidance in axial direction is demanded. Double-row angular-contact double-direction ball bearings are particularly sensitive to errors of alignment. A variant of double-row angular-contact ball bearings is widely implemented in the automobile industry, especially in the hubs units of car wheels. But the construction of these bearings is very specific, most often with a split inner ring and other, untypical sizes and designations. They are ever more fully integrated with a hub.
