A spring force component tester for determining a load distribution on each end of a spring of generally cylindrical shape using three, mutually-parallel load cells. One tester includes a lower plate and an upper plate movable with respect to the lower plate. Each plate includes a plurality of recesses and a load cell positioned in each recess. Each plurality of recesses is positioned such that a center of each recess is a point on a circle coaxial to the plate. The tester also includes a data logger that obtains and stores load cell outputs from the load cells and spring tester electronics that obtain height measurements of the upper plate and send a trigger signal to a computer. The computer executes application software when the computer receives the trigger signal that reads the load cell outputs stored in the data logger, and calculates a spring force acting along the spring axis between approximately 0.5 Newton and 100 Newton.

A hydrostatic positive displacement machine has a cam ring for adjusting the displacement volume thereof. This cam ring is guided in translation by approximately diametrically arranged outer circumferential surface segments on associated inner surface segments of a housing of the positive displacement machine.
