    Eaton JMF Swing Drive Motors

    Eaton JMF Swing Drive Motors


    Eaton JMF motors are fixed displacement axial piston motors for swing applications. They provide reliable, high performance with a compact design and high power density. Typical applications include: excavators, concrete pumps, cranes and drilling.

    An improved design ensures higher start up torque and overall efficiency. Mechanical shocks are minimised through an integrated valve design; this gives a smooth, energy-absorbing transition during acceleration and deceleration.

    Every JMF swing motor has an integrated fail-safe mechanical parking brake, brake release valve, shockless relief, and anti-reverse valves. Other features include:

    • Compact integrated planetary reduction gearbox;
    • Smooth and precise positioning eliminates mechanical shocks;
    • Higher mechanical and volumetric efficiency helps reduce power loss.
