Abstract
A wheel bearing assembly is provided which can prevent lowering of the life of a bearing assembly due to entry of muddy water into the bearing assembly through a gap between fitting surfaces of a first inner member and a second inner member. These members are rotatably supported by mounting rolling elements between double-row raceways formed on an inner peripheral surface of an outer member and raceways formed on outer peripheral surfaces of the first and second inner members. A stem formed on the second inner member is inserted into a hole formed in the first inner member, and a tip of the stem is caulked to hold the first and second inner members in a coupled state. An annular groove is formed in an outer periphery of the stem. A seal ring is mounted in the annular groove.
