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