Abstract: In a piston pump assembly, cradle bearings support a swash plate on an inner surface of a housing assembly. The cradle bearing and/or the corresponding portion of the housing inner surface may have undercut portions allowing deflection of an inward portion of the cradle bearing when the swash plate is subjected to pressure forces from hydraulic fluid compressed within pump cylinders by the pump pistons. Deflection of the cradle bearings allows increased contact pressure to be further distributed across the engaging surfaces of the swash plates and the cradle bearings.

Abstract translation: 在活塞泵组件中，支架轴承支撑在壳体组件的内表面上的斜盘。 托架轴承和/或壳体内表面的相应部分可以具有底切部分，当斜盘受到泵活塞在泵缸内压缩的液压流体的压力时，能够使托架轴承的向内部分偏转。 支架轴承的偏转允许增加的接触压力进一步分布在斜盘和摇篮轴承的接合表面上。
