摘要： The bearing assembly includes a rolling bearing including a rotatable raceway member and a stationary raceway member. This bearing assembly also includes a to-be-detected member carried by the raceway member and having a magnetic characteristic which cyclically varies in a direction circumferentially of the to-be-detected element and has a cycle matching with one complete rotation of the raceway member, a magnetic sensor unit carried by the raceway member in face-to-face relation with the to-be-detected member, and a magnetic detecting circuit to supply an electric power to the unit and to process an output signal from the unit to provide an output to an external circuit. The magnetic characteristic of the to-be-detected member represents a substantially sinusoidal waveform rising and falling more steeply than a sinusoidal waveform at a zero-crossing point.

In face-to-face relation with this to-be-detected portion 1, a magnetic detecting portion 2 is secured to a stationary race member 33. The magnetic detecting portion 2 is made up of magnetic sensors arranged in a direction circumferentially of the race members 32, 33 and each capable of providing an analog output. A differential output generating means 7 is provided for processing a differential output of the adjoining two magnetic sensors 2a and 2b as an encoder signal for one phase.
