-8- WEAR SLEEVE OIL SEAL ABSTRACT OF THE DISCLOSURE An inner peripheral seal ring on the inner periphery of the wear sleeve to seal axial flow of oil and permit heat radially transferred through the wear sleeve for cooler operation of the seal on the wear sleeve. The end of the shaft is formed with a chamfer or other form of recess and the end of the wear sleeve is formed with a taper or lift producing a recess or entrapped area on the inner periphery of the wear sleeve. A seal ring is formed in the recess of the wear sleeve which engages the chamfer on the end of the shaft to form an oil seal preventing axial flow between the wear sleeve and the shaft. A major portion of the interface between the shaft and the wear sleeve is a metal to metal interface providing a good heat transfer from the shaft to the sleeve of the sealed assembly.
