Abstract
A rolling bearing with a rotation sensor includes an inner race and an outer race, one of which is a rotating race and the other of which is a stationary race. An annular magnetic encoder alternately magnetized in opposite polarities in its circumferential direction is mounted on the rotating race. A magnetic sensor configured to detect the changes in magnetic flux when the magnetic encoder is rotated is mounted in a resin sensor housing mounted on the stationary race. The sensor housing is made of a resin material including a resin composition containing polyphenylene sulfide, an inorganic filler, and glass fiber.
