The invention relates to a rotation-slide bearing ( 25 c) which comprises an inner first bearing element ( 31 ) with an outer peripheral surface ( 31 a) and an outer second bearing element ( 32 ) with an inner peripheral surface ( 32 a). 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 ( 31 a) of the inner first bearing element ( 31 ) and/or in the inner peripheral surface ( 32 a) 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 ( 42 a , 42 b) with a slide surface ( 42 c) 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 ( 32 c) facing it. At least one second oil groove ( 32 c) that extends in an approximately radial relation is disposed in the slide surface ( 42 c) or in the lateral surface ( 32 c) supported by it. The oil grooves ( 46 a , 46 b , 38 ) communicate in the zone where they face one another. |
