FIELD: machine building.
SUBSTANCE: invention is related to machine building, namely to bearing units of transmission mechanisms. Suggested bearing comprises internal ring equipped with gear rim with external teeth having convex helical channel working surfaces, rolling elements with concave helical channel teeth working surfaces that correspond to internal ring, external ring that comprises cartridge and inserts fixed on its internal surface that bear teeth working surfaces. External ring inserts are made in the form of previously bent rods of circular section, axes of which are located along theoretical helical line of channel tooth. Inserts are fixed on external ring cartridge with the help of undetachable joint: soldering, welding, glue, etc. In process of bearing operation rolling elements and rings are in strict kinematic connection with each other. This interconnection is also not broken in unloaded zone of bearing.
EFFECT: simplification of external ring manufacture.
