An apparatus to simulate the thermal behavior of a tapered roller bearing was constructed and used to determine tapered roller bearing thermal behavior. Bearing specimens can be loaded axially and/or radially while rotating. Shaft heating is also provided and mechanical losses measured. An infrared scanner and thermocouples allow for temperature measurement. An analytical model of the bearing and bearing/housing system was also developed and is presented. The model is capable of considering various modes of bearing operation. Experimental and theoretical resistances are compared. Typical thermal resistances from shaft to housing were found to be of the order of 1 K/W.
