The Sundstrand MF20 Series is an axial piston motor for closed circuit applications.
The output speed is proportional to the flow rate of the input fluid. The output torque is proportional to the differential between high and low pressure sides of the fluid circuit. The direction of motor (output) shaft rotation depends upon which port the fluid enters the motor.
The Series 20, are well-engineered and easy to handle. The full-length shaft with a highly efficient tapered roller bearing arrangement offers a high loading capacity for external radial forces. High case pressures can be achieved without leakage even at the lowest temperatures by using suitable shaft seals. The modular construction of the units simplifies the production of a wide variety of model options while limiting the number of different components involved.
