Abstract
An arc-shaped rolling bearing segment (14) comprising a cage (16) and rolling elements (15) for a swash plate pivoting bearing of a hydraulic axial piston machine is characterized in that the cage (16) and the support peg (17) are made as a single piece out of a polymer material, and the support peg (17) is surrounded, at least over a part of its axial length, by a metal ring (18).
Claims4
A swash plate pivoting bearing for a hydraulic axial piston machine in which rolling bearing segments (14) are arranged between a hollow cylindrical bearing surface (12) for the swash plate (10) in a housing (4) and a cylindrical bearing surface (11) on the swash plate (10), which rolling bearing segments (14) are retained in arc-shaped cages (16) that are configured as solid cages and comprise a support peg (17) for repositioning the cage (16) upon displacement from a desired position, said support peg (17) extending parallel to the rolling element pockets and projecting beyond the cage width while being connected to a readjusting device, characterized in that the cage (16) and the support peg (17) are made as a single piece out of a polymer material, and the support peg (17) is surrounded, at least over a part of its axial length, by a metal ring (18) which comprises a projection (19) on its inner peripheral surface.
