A device monitors the operating temperature of at least one set of bearings in a plurality of sets of bearings. The at least one set of bearings is arranged between a shaft and a carrier. The carrier has at least one temperature sensor that senses the temperature of the at least one set of bearings and generates a signal representative of an operating temperature of the at least one set of bearings. The at least one temperature sensor is operatively electrically connected to at least one controller. The controller processes the signal from the temperature sensor, including determining the operating temperature of the respective at least one set of bearings and whether the operating temperature of the respective at least one set of bearings exceeds at least one threshold temperature. The controller memory holds a unique identifier associated with the at least one bearing set.
