摘要： A wheel bearing device is proposed which maintains long life even under high-load, high-temperature conditions. On the surfaces of inner rings and tapered rollers of a multiple-row tapered roller bearing rotatably supporting a wheel, carburized, nitrided layers are formed which contain 0.80 wt % or more carbon and have a Rockwell hardness of 58 or over with the residual aaustenite content being 25-35 vol % to improve mechanical properties and fatigue characteristics of these parts and also keep the surface layers of these parts of suitable toughness, thereby improving the life of the wheel bearing device in a high-load, high-temperature environment. Also, an annular recess is formed in the inner periphery of the outer ring at a portion between the rows of the raceways.

The assembly includes a fixed member fixed to a vehicle body, and a rotary member rotatably supported in the stationary member through a bearing and mounted to a vehicle wheel. An annular sensor is fitted to a knuckle, which is a part of the fixed member, on the inboard side of the bearing. A sensor seal is fitted to the annular sensor and has a seal lip kept in slide contact with a seal land formed on a constant-velocity joint outer ring, which is a part of the rotary member, to define a sealed space on the inboard side of the bearing. An encoder is mounted on a bearing inner ring, which is a part of the rotary member, in the sealed space. The sensor element is disposed in the sealed space, opposite the encoder.
