Abstract
A sensor bearing assembly rotatably couples a pulley sheave with a shaft and includes an inner member with a central bore receiving a portion of the shaft, two axially spaced inner raceway surfaces and a central portion between the raceways. An outer member is disposed about the inner member and disposeable within the sheave bore to rotatably couple the sheave with the shaft. The outer member has two axially spaced outer raceway surfaces disposed about the two inner raceway surfaces and a central portion between the outer raceways and disposed about inner member central portion to define an annular cavity. An annular detection member is disposed within the annular cavity and coupled with the outer member and a sensor is disposed within the annular detection member and connected with the inner member central portion. The sensor is configured to sense angular displacement of the detection member about the bearing axis.
