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.

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 arrangement having: a first element having an inner race and a first bearing surface; a second element, pivotable relative to the first element about a first axis, and having an outer race and a second bearing surface that cooperates with the first bearing surface to form a plain bearing. The bearing arrangement also includes a roller element disposed between the inner and outer races to form a rolling bearing. The inner and outer races are arcuate and subtend an angle of less than 360° about the first axis.

The invention relates to a pivot locking device of two bearing elements (102, 103) oriented towards a common axis, in which one or both bearing elements (102, 103) are pivotable about a common pivot axis (22), with a first bearing element (102), which comprises a perforation (104), with a second bearing element (103), which comprises a perforation (106), wherein the first and second bearing elements (102, 103) are oriented in alignment to one another with the perforations (104, 106), with a chamber (124) provided on the first bearing element (102), which chamber comprises a circulatory path for circulatory elements (129) and is open to the second bearing element (103) and, by a connecting surface (118) facing to the chamber (124), is closed on the second bearing element (103), with a plurality of circulatory elements (129) arranged in the chamber (124), with an catch (121) arrangeable on the second bearing element (103), which catch engages into the circulating chamber (124) and is positioned between circulatory elements (129) and, in a pivot movement of the second bearing element (103) to the first bearing element (102), displaces the circulatory elements (129) in the chamber (124) along the circulatory path, and with a locking element (107) arranged on the first bearing element (102), which locking element, in an unlocking position (109), unblocks the circulatory path for the circulatory elements (129) in the chamber (124) and, in a locking position (108) of the locking element (107), blocks a displacement movement of the circulatory elements (129) along the circulatory path of the chamber (124).

A bearing assembly having an inner race, an outer race, and a plurality of rollers positioned between the inner race and the outer race. A pad is attached to the inner race and a bed is attached to the outer race. A timing mechanism is slidably mounted to the pad and the bed. Preferably the pad and bed are made of plastic and the inner race is embedded within the pad and the outer race is embedded within the bed.

A swash plate bearing is disclosed. The swash plate bearing may have an arcuate cage member having at least one flange and a plurality of rolling elements rotatably coupled to the at least one flange. A coupling seat extends laterally from the at least one flange, the coupling seat may have an insertion hole. A link member may be rotatably coupled to the cage member, the link member having a central portion positioned between a first terminal portion and a second terminal portion. A first stem connects the central portion to the first terminal portion and a second stem connects the central portion to the second terminal portion. The central portion is positioned in the insertion hole.

The present disclosure relates to a coupling assembly for a variable displacement hydraulic unit. The coupling assembly may have a rotatable swashplate, a swashplate bearing including a cage and a plurality of rollers mounted on the cage, a pin fixed to the swashplate, and a coupling member rotatably supported on the pin. The coupling member is configured to contact a portion of the cage to move the swashplate bearing upon rotation of the swashplate
