Abstract

A bearing assembly includes two tapered roller bearings having inner and outer rings and tapered rollers therebetween. The inner rings are mounted to a first machine part, and the outer rings are mounted on an adapter sleeve on a second machine part. The adapter sleeve has a first end axially fixed relative to the second machine part and a second end axially spaced from an axial stop of the second machine part by an axial gap. At a non-operating temperature, such as 20° C., the gap has a width of about 30 μm to 250 μm, and at an operating temperature of over 50° C. the gap disappears and the second end contacts the axial stop. The width of the gap at the non-operating temperature is selected to produce a predetermined preload on the bearing assembly at the operating temperature.
