The motion characteristics of a slipper bearing in the swash plate type piston pump and motor have been investigated experimentally and theoretically. The motion of the slipper bearing has been measured by means of eddy current displacement sensors. The mathematical model of the slipper bearing has been indicated considering asperity contacts of surface roughness, comparing experimental results. It is found that (1) the numerical calculation results correspond to experimental ones, (2) the slipper bearing may swing at the same cycle as rotation of the swash plate, (3) the motion of the slipper bearing in pumping action differs greatly from that in motoring action, and (4) the friction phenomena between the cylinder and the piston, and on the spherical bearing affect on the motion of the slipper bearing.
