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.

Disclosed is a crane, in particular for offshore application. The crane includes a bearing the assembly between a pedestal and a carrier frame. The bearings are distributed over the height of the support structure and include upper bearing, which include a radial contact rolling bearing including rolling elements and a smooth cylindrical raceway, coaxial to the axis of rotation. The radial contact rolling bearing allows a longitudinal translational degree of freedom of the rolling elements over the height of the cylindrical raceway.

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).
