This type is produced according to TU 37.006.133. contact angle? this type is from 10 to 18 °, which allows it to be operated under conditions of high radial and axial loads. A characteristic feature of the products of this series is the presence of springs on the outer ring.

Bearings of this type are currently produced only at one enterprise in the country - Aviation Bearing Plant OJSC, or rather, in its branch at 15 GPP in the city of Volzhsky in two modifications: 2-17722 L1 (second class of accuracy, with a brass separator) and 4-17722L1 (fourth class).
