Abstract: In axial-piston, hydraulic pumps and motors, the thrust loadings of the pistons on their bearing supports vary proportionally to pressures in the unit and also circumferentially around the bearing supports. By employing hydrostatic button bearings pressurized in ''''sets'''' around the bearing support with at least one set pressurized with the unit''s inlet pressure and another ''''set'''' pressurized by the unit''s outlet pressure, improved bearing performance is achieved. Also, certain surface configuration forming the sills and recesses of the individual buttons can enhance bearing performance.

Abstract: A circular hydrostatic button bearing which is supported by its skirt loosely received in associated pressurized pocket, achieves attitude stability by a chamfered circular edge on a substantially flat bearing pad area having several sills that oppose the thrust forces induced by a runner surface that is supported by the button bearing. The inner sill has a configuration to achieve a proper geometric balance.
