Project Description

LiftingMotion electric screw jacks are motorized screw jacks driving by electronic motors. The load capacity is from 0.25T to 100T. It has ductile iron housing(LMK0.25t and LMK0.5t has aluminum housing), tapered roller bearing, and high-strength bronze worm gear. We offer a large range of motors to suit your application such as helical gear motor, stepper motor, servo motor, single-phase or three-phase ac motor, and 12v /24v DC motor.

  • 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.
