Abstract:
A wheel bearing assembly comprising:an outer member having a pair of outer raceways at an inner periphery thereof; an inner member having a pair of inner raceways at an outer periphery thereof disposed opposite said outer raceways; and rolling elements mounted between said inner and outer raceways; wherein one of said outer member and said inner member includes a wheel-mounting flange, said wheel-mounting flange having an outer face facing in a generally axially outward direction and constituting a circumferentially-extending brake rotor-mounting surface; wherein a film is disposed on said brake rotor-mounting surface of said wheel-mounting flange so as to be disposed between said brake-rotor mounting surface and an abutment surface of a brake rotor when the brake rotor is mounted to abut said brake rotor-mounting surface; and wherein said circumferentially-extending brake rotor-mounting surface is inclined relative to a radial direction so as to have an overall frusto conical shape that is concave in the axially outward direction, an incline of said brake rotor-mounting surface being 20 minutes or under.
