ABSTRACT:
One thrust race of a two-race thrust bearing has a magnetic field sensor mounted on a lip extending axially from the outside diameter of the thrust race. The other thrust race has a magnetic field source. The race with the magnetic field source rotates; the race with the sensor is fixed. The number of times alternate magnetic poles on the rotating thrust race is sensed by the sensor per unit of time indicates the speed of the rotating thrust race.
