Abstract
A saddle bearing liner (30) for a variable displacement axial piston pump (10) includes two axially-spaced apart bearing surfaces (62, 64) with an offset central section (54) integrally joining them. A hollow projection (80) extends radially from the convex side of the pressure bearing section (50) and is received with a recess (82) of the housing (12) to locate the liner (30). The liner (30) has radially extending ledges (70, 72) which mate with surfaces (74, 76) of the housing (12) to inhibit skewing of the bearing liner (30) relative to the axis of the bearing surfaces (62, 64). The projection (80) is hollow and opens to the bearing surface (62) so that pressurized fluid from the housing (12) can be injected between the bearing surface (62) and the mating surface (22) of the swashblock (20). The projection (80) also prevents the liner (30) from rotating about the bearing surface axis.
