    Screw Jack Actuators

    Our SJWG series screw jack actuators provide a new mature solution for the linear motion of heavy loads, the screw jack actuators, motors, geared motors and other accessories are modularized and organically combined to achieve heavy-duty lifting and lateral movement in the industrial field. At the same time, the high-sealing protection level is more suitable for normal working in harsh working environments is a cost-effective solution to replace hydraulics, reduce environmental pollution, save energy, and reduce maintenance costs.
    Load capacity: 2.5-ton, 5-ton, 10-ton, 20-ton
    The special precision guide bearing design offers better stability and lateral force capability.
    Double-sealed to prevent dust and dirt from entering the cylinder, with IP55, IP56 protection for long term operation in harsh environments.
    Precise position control with a control accuracy of 0.1 mm.
    High rigidity and impact resistance.
