Bearing with sensor
A bearing assembly with a sensor, includes an annular, synthetic resin sensor holder supported on an outer race using a circumferential groove of the outer race so as to be strongly fixed in position by a spring member having circumferential half-split elastic recovery portions. The spring member is a square sectional wire and includes a main portion fitted in an annular groove of the sensor holder, and opposite end portions that circumferentially protrude from the annular groove and are located inside an open recess of the sensor holder. The opposite end portions of the spring member overlap axially when fitted in the annular groove, and abut and are deflected when one of the end portions is shifted to remove the overlapping. Forces caused by elastic recovery of the deflected end portions increase the force of the main portion pushing the sensor holder in a radially outward direction.
