Wheel bearing unit with positively engaging connection of two annular parts which can be fitted one into the other

摘要

So that no forces which have a negative effect on the bearing can be exerted during the manufacture of the axial fixing device as a result of plastic deformation, a circumferential restriction (7) is provided on the projection (6) which is to be deformed, the centre of which constriction (7) lies approximately in the region of the edge (5') of the bearing ring (5).
