In an eccentric bearing arrangement for a pump shaft ( ) comprising an eccentric ring ( ) that is fixedly attached thereto, and further comprising a needle roller bearing that is arranged on an outer peripheral surface of the eccentric ring, a stop washer ( ) is retained in a circumferential groove ( ) of the needle roller bushing ( ) and is surrounded radially by the adjoining flange ( ) of the needle roller bushing ( ), and the stop washer ( ) comprises an axially inward open annular groove ( ) in which the cage ( ) is guided.

Radial piston pump

A radial piston pump comprising a rotating pump shaft (,), one portion (,) of which is connected to an eccentric ring (,) which is arranged rotationally fast thereon, said radial piston pump further comprising a needle roller bearing arranged on an outer peripheral surface of the eccentric ring (,), pump plungers (,) arranged radially of the pump shaft (,) in a star pattern in a pumping housing supported by end faces on the needle roller bearing, the bearing being configured as a self-contained, inseparable assembled unit in which the eccentric ring (,) is arranged within the needle roller bearing between rims (,) of the needle roller bearing which advantageously reduces the axial design space requirement and simplifies assembly.
