Abstract

A bearing assembly is configured to rotatably support a first machine part in a second machine part and includes first and second rolling-element bearings. The rolling-element bearings are installed in the bearing assembly with an axial preload or an axial clearance. The second machine part includes a first conical abutment surface, and the first rolling-element bearing includes a bearing ring having a second conical abutment surface facing the first conical abutment surface of the second machine part. An intermediate ring is disposed between and abuts the first and second conical abutment surfaces. The bearing ring and the second machine part are metal, and the intermediate ring is formed from a material that has a higher coefficient of thermal expansion than that of the bearing ring and second machine part.
