Abstract:
A bearing provided with a rotation sensor comprises an outer ring, an inner ring and rolling elements, and a magnetic ring is engaged with the inner diametral surface of the outer ring. Thus, a highly reliable bearing provided with a rotation sensor exerting no bad influence on a magnetic sensor can be provided.
