摘要

The arrangement (1) has two tapered roller bearing rows (2) axially spaced from each other. A three-point bearing (9) is axially arranged between the bearing rows. An outer ring (4) of the three-point bearing comprises a circular arc shaped path profile in a sectional representation that includes a bearing axle (3).
