In industrial applications, the axial piston pumps, which are essential elements of hydraulic power transmission systems, work according to load bearing principles between two moving surfaces. It is important for these surfaces to carry these loads without contacting each other. The slipper bearings integrated into axial piston type pumps enable bearing these loads without a contact between the surfaces. This study investigates slipper bearings which play an important role in load carrying capacity (LCC) of axial piston pumps. Experimental studies show that LCC values differ according to the slipper bearing type and orifice diameter. The changes of slipper bearing geometry have bigger effects on load carrying capacity.
