It has become very important to improve hydraulic motor efficiency, especially in the starting and low-speed ranges, for finer hydraulic operation. From this point of view, this report aimed to provide technical data to help improve a swashplate-type axial piston motor's performance, particularly concerning the friction characteristics between the piston and cylinder. The effects on its friction characteristics are experimentally examined with regard to supply pressure, surface roughness, oil temperature, rotational speed, and so forth. The results show that the friction force depends heavily on the supply pressure, rotational speed, phase angle, and piston surface roughness, and that the reduction of friction force seems to be possible by changing the cylinder material or by the piston equipped wth lubrication holes.
