A wheel speed detector for detecting a relative rotating speed between an outer ring and an inner ring by means of a magnetic sensor in association with a magnetic ring. A stationary seal member is fixed to the stationary ring and a rotatable seal member is fixed to the rotatable ring. The seal members engage to seal a gap between the inner ring and the outer ring. The magnetic sensor is fixed to a radial inner surface of the stationary seal member and the magnetic ring is fixed to a radial outer or a radial inner surface of the rotatable seal member and surfaces of the magnetic ring other than that fixed to the radial inner surface of the rotatable seal member are covered with a seal lip.

Wheel speed detector having stationary seal member for mounting magnetic sensor

This wheel speed detector is constructed of a magnetic sensor and a magnetic ring and is integrated with the inside of a seal device. The magnetic ring constitutes a part (core bar) of the seal device. This arrangement can enable the compacting and reduction in the number of components and improve space saving and assembling workability.

A rotating member supporting apparatus has a rotating shaft which is inserted to a bore formed in a support member. A rolling bearing is interposed between the rotating shaft and support member and rotatably supports the rotating shaft. The bearing includes an inner and outer rings which have resistance to heat and corrosion, and a plurality of rolling elements rollably arranged between the inner and outer rings. The rolling elements are formed of ceramic material.
