ABSTRACT:
A bearing on a steering shaft has an elongated inner race and an elongated outer race with rolling elements between the two races. The inner race is rotatable with respect to the outer race. An encoder is mounted on the inner race. Sensors in a detachable sensor mount sense the radial magnetic field from the encoder as it rotates past the sensors.
