ABSTRACT:
A vehicle wheel rolling bearing has a sealing device integrated with a magnetic encoder. A semi-float type bearing apparatus has said rolling bearing which can protect a magnetic encoder and improve the sensing ability of the detecting sensor. The rolling bearing has an inner member with a wheel hub having a wheel mounting flange and an inner ring formed with inner raceway surfaces. An outer member is formed with double row outer raceway surfaces opposite the inner raceway surfaces. Double row rolling elements are between the raceway surfaces. Sealing devices include an inboard sealing device with an annular seal fitted on the outer member. A pulsar ring is mounted on the inner member and has an encoder mounted on a cylindrical holding portion. The encoder is arranged opposite to the annular seal. The encoder includes magnetic poles formed by magnetic powder with alternating polarity along its circumferential direction. A detecting sensor passes through the cylindrical portion of the seal and opposes the encoder. A predetermined air gap is kept between the encoder and detecting sensor.
