XM-F40L, XM-F75F and TX-F75F swash plate axial piston motors are reversible hydraulic components. The same component can be used as both oil motor and oil pump (directly interchanged with ZBD40 and ZBD75 pumps). The motor has the advantages of compact structure, small volume, light weight, high working pressure and high efficiency. It can be combined with other components (valves, hydraulic cylinders, etc.) to form a closed or open hydraulic system. It is suitable for construction machinery, lifting and transportation machinery, construction machinery, machine tools, ships, mining, metallurgy and other machinery.
