ABSTRACT:
A detector for detecting the rotating speed of a wheel bearing having a pulser ring mounted between bearing rings of a wheel bearing at one end thereof. One of the bearing rings is adapted to rotate together with a wheel and the other is fixed. A ring is provided axially outside of the pulser ring and press-fitted on the fixed bearing ring. A rotating speed sensor is mounted on the ring and has a detecting portion inserted in a hole formed in the ring. A seal member is provided in the space between the ring and the rotatable bearing ring to seal the space. In another arrangement, the ring is mounted on the fixed one of the bearing rings and the detected portion of the pulser ring is located opposite to the detecting portion of the rotating speed sensor with a radial gap defined therebetween.
