Abstract

A rolling bearing unit with a rotation speed sensor comprising a stationary member, a rotatable member having a second raceway, a plurality of rolling members rotatably provided between the first raceway and the second raceway, an encoder fixed to the rotatable member and to be concentric with the rotational axis thereof and having a detected portion the characteristics of which are adapted to alternately change, and a sensor fixed to the stationary member to detect changes in the magnetic characteristics of the encoder to produce signals as the rotatable member rotates, and the sensor having a detecting portion which is opposed to the detected portion of the encoder with a clearance therebetween at a circumferential location where the change in the clearance is minimized when subjected to a load from outside.
