    Curved Jaw Couplings

    Jacks used alone or in multiple arrangements require couplings to transmit power to the input shaft, it is important to select the best option based on torque and rotational speed requirements. SIJIE Industries provides SFC curved jaw couplings for use with jacks and the torque up to 1040N.m.
    Zero backlash, flexible shaft.
    Detachable design, easy installation.
    Couplings assembled by pressing a polyurethane sleeve into bubs on both sides.
    Can absorbs vibration、parallel、angular misalignment and shaft end-play.
    Resistance to oil and electrical insulation.
    Identical clockwise and anticlockwise rotational characteristics.
    Clamp type, Aluminum Alloy Body.
