An arc-shaped rolling bearing segment ( ) comprising a cage ( ) and rolling elements ( ) for a swash plate pivoting bearing of a hydraulic axial piston machine is characterized in that the cage ( ) and the support peg ( ) are made as a single piece out of a polymer material, and the support peg ( ) is surrounded, at least over a part of its axial length, by a metal ring ( ).

Swash-plate drag bearing

A wobble drive in an axial piston machine, particularly the axial piston pump of a high-pressure cleaning device, having a wobble body (,) rotatable around an axis of rotation (D) and a wobble plate (,) driving with its front side at least one piston (,) positioned parallel to the axis of rotation D, a roller bearing (,) positioned between the wobble body (,) and the wobble plate (,) exhibiting a bearing axis inclined to the axis of rotation (D). In order to insure even at elevated rotary speeds of the wobble body (,) and thus also of the rolling bodies (,) that the rolling bodies (,) are securely held in their races (,) in spite of the elevated centrifugal forces acting on them, it is proposed that the wobble plate (,) be provided with a rim (,) overlapping the wobble body (,), with the rolling bodies (,) being positioned between the rim (,) and the wobble body (,).
