The electric screw jack is an electric screw jack driven by an electric motor. The load capacity is from 0.25T to 100 T. It has ductile iron housing (LMK0.25t and LMK0.5t have an aluminum housing), tapered roller bearings, and a high-strength bronze worm wheel. We offer a wide range of motors to suit your application such as helical gear motors, stepper motors, servo motors, single or three-phase AC motors, and 12v /24v DC motors.

  • Cubic screw jack type with compact and versatile cubic housing
  • Translating(traveling screw) and rotating (traveling nut) configurations
  • Trapezoidal spindle (self-locking) and Ball Screw spindle (high efficiency) version
  • Design option: Standard, Anti-rotation, Anti-backlash, or Safety nut
  • Standard and custom end fittings, mounting options, and drive shaft

You can trust us on high quality, on-time delivery, controlled costs, and reduced risk.
