Abstract
A rolling bearing unit with rotating speed sensor comprising a stationary ring having a first raceway, a rotatable ring placed concentric with the stationary ring and having a second raceway, a plurality of rolling elements provided between the first and second raceways, a magnetic tone wheel supported by the rotating ring to rotate together with the rotating ring and having cutouts for an encoder portion, and a sensor supported by the stationary ring to be opposed to the tone wheel and having a detecting portion opposed to the encoder portion with a small gap therebetween, wherein the cutouts are produced through a punching stroke from the side of the magnetic metal plate which is not faced to the small gap to the side of the magnetic metal plate which is faced to the small gap in the assemble state.
