Description: Radial piston hydraulic motors come with high displacement and torque. It is a low noise motor due to an eccentric crankshaft and low vibration frequency of five piston design. Due to high starting torque and good stability it rotates under very low speed. There are seals between piston and cylinder, which give high capacity efficiency and less leakage with high reliability. Oil is supplied by the pump to the distributor valve spool of the motor. The valve directs the oil into two cylinders. The crankshaft rotates as piston in these cylinders push down on its drum. The remaining cylinders exhaust their oil back through the valve to exhaust port. The valve is keyed to the crankshaft so both rotate together and port oil to each cylinder in succession. Roller bearings are used in between crankshaft and connecting rod, which give high mechanical efficiency. These motors have reversible rotation and output shaft can bear axial and radial loads. These motors have versatile construction design, high power and low weight.
