Abstract
A wheel support bearing assembly includes an outer member and an inner member, each having a raceway surface. The inner member is made up of a combination of a rotatable ring, having its outer periphery formed with a vehicle body fitting flange, and a separate member. Each of the outer member and the flanged rotatable ring has a surface region representing a thermally refined structure formed by means of martensite hardening and high temperature tempering and also has a core region representing an as-forged structure made up of ferrite and pearlite.
