Abstract
A cam (23) provides a rotating guide surface (33) for the cage (30) of the roller elements (25, 26) of a bearing (22) used to support the load on the cam of an axial piston pump (11) that uses pistons (17, 18) having no shoes or slippers. The rotating guide surface (33) is provided by extending a cylindrical surface (34) from the rotating cam (23) through the inside diameter, or around the outside diameter of the rolling element cage (30), concentric to the centerline of rotation.
