The bearing10co-operates with an abutment18on the rotor to form a thrust interface. The abutment has a planar surface19with an outer diameter A. The bearing10has a cylindrical radially outer surface, a central bore13with a diameter B and two end faces12. One end face has an axially inclined thrust surface16having an inner edge with a diameter C and an outer edge with a diameter D whereinin-line-formulae description="In-line Formulae" end="lead"?C<A<D and B≦C≦1.5B.in-line-formulae description="In-line Formulae" end="tail"?
