The present disclosure relates to an axial piston machine, such as a pump or motor. The axial piston machine, in on example, includes a pivotable displacement adjustment plate, the displacement adjustment plate having a first side supported by a first hydrostatic support arrangement and a second side supported by a second hydrostatic support arrangement. Further, in the axial piston machine one or both of the hydrostatic support arrangements include a large area support and a small area support which can be fluidly separated from each other.

A cradle bearing for supporting a swashplate of a variable hydraulic axial piston. The cradle bearing is of an angular ball bearing type or comprises, with respect to the bearing axis, a tapered inner race and/or a tapered outer race. A swashplate for a variable hydraulic axial piston unit including a first and a second cradle bearing zone spaced to each other in axial direction of a swashplate tilt axis, suitable for supporting the swashplate in a housing of a variable hydraulic axial piston unit, wherein the first cradle bearing zone is inclined with respect to the swashplate tilt axis. A variable hydraulic axial piston unit of the swashplate type including a swashplate which is supported rotatable in the housing of the variable hydraulic axial piston unit at a first bearing zone by a tapered bearing and at a second bearing zone by regular cylindrical cradle bearing or a journal bearing whose axis is aligned with the swashplate tilt axis.

An inline piston pump that is efficient, manufacturable, and durable. The angled bearing surface within the pump that it contacts drives the piston and rotates with the cylinder.

A pivot cradle bearing (1) for an axial piston machine, including a bent cage segment (2), in which rolling bodies are guided, which are arranged between two bearing parts which can be pivoted with respect to one another, wherein a synchronization device (4), which is designed for synchronizing the relative movement of the bearing parts with the displacement of the cage segment (2), includes a pivoting lever (5) which is mounted in the cage segment (2). An articulated bearing (6) is provided for mounting the pivoting lever (5) in the cage segment (2), the articulated bearing having an asymmetrical design with respect to a tangential plane (TE) lying centrally between an inner circumferential surface and an outer circumferential surface of the cage segment (2).

A bearing attachment system for a pump product having a seal carrier and a cover plate. The attachment system is configured to produce a force deflection curve that provides a clamping force on a pair of tapered roller bearings such that a tight bearing endplay on the tapered roller bearings is maintained through a full range of manufacturing tolerances. The geometric shape of the cover plate and the top surface of the seal carrier provide the desired deflection characteristics.
