Vehicle wheel bearing seal with integrated coding element - uses pulse generator with evenly spaced windows between permanent magnet and stationary sensor

The wheel bearing seal (1) has an annular part (8) attached to the stationary roller bearing ring (4), supporting a permanent magnet (14). A second annular part (9) is attached to the rotating bearing ring (3) with a pulse generator zone and a flexible sealing zone cooperating with the first annular...

More Information
Summary:The wheel bearing seal (1) has an annular part (8) attached to the stationary roller bearing ring (4), supporting a permanent magnet (14). A second annular part (9) is attached to the rotating bearing ring (3) with a pulse generator zone and a flexible sealing zone cooperating with the first annular part. The permanent magnet is aligned with a stationary sensor (11) with the pulse generator located between them provided by a number of evenly spaced windows. The sensor is taken up by a connection head (10) made of plastic material. USE - For detecting wheel rotation rate for vehicle anti-locking braking system.
