Wheel bearing assembly

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;
• 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.
