The invention relates to a rotation-slide bearing (25c) which comprises an inner first bearing element (31) with an outer peripheral surface (31a) and an outer second bearing element (32) with an inner peripheral surface (32a). The outer bearing element (32) encloses the inner bearing element (31). At least one first oil groove (38) that extends in an approximately axial relation is provided in the outer peripheral surface (31a) of the inner first bearing element (31) and/or in the inner peripheral surface (32a) of the outer second bearing element (32). In order to improve a rotation-slide bearing of the aforementioned kind in such a way that it can absorb radial and axial forces and has good slide properties, a support shoulder (42a, 42b) with a slide surface (42c) is associated with one of the two bearing elements (31) on one or both sides and axially supports the bearing element (32) with its lateral surface (32c) facing it. At least one second oil groove (32c) that extends in an approximately radial relation is disposed in the slide surface (42c) or in the lateral surface (32c) supported by it. The oil grooves (46a, 46b, 38) communicate in the zone where they face one another. |
