Abstract: 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.

Abstract: 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.
