Abstract
A vehicle wheel hub bearing unit is disclosed, in which the outer race (10) of the bearing has a radial bearing flange (11) providing an axially protruding edge (12) adapted for being folded by rolling in a radially outer direction to secure for rotation a flange (21) of the brake member (20). The brake flange (21) is clamped between the rolled edge (12') and a peripheral undeformed radial edge (13) of the same bearing flange (11). The hardness of the material forming the axial edge (12) to be deformed by rolling is between about 200 HV and 300 HV. This edge (12) protrudes axially from the brake flange (21) by a length (d) shorter than 5 mm. The thickness (e) of said edge (12) is within 1 and 3.5 mm. The axial thickness (a) of the edge (12') deformed by rolling against the brake flange (21) is less than 3.5 mm and the axial thickness (c) of the undeformed radial peripheral edge (13) exceeds said axial thickness (c) by a length x=0.4.div.1 mm.
