NMRV Worm Gearbox Motor Reducer - Screw Jack Systems

Jacton screw jacks and lifting systems offer wide-ranging lifting and positioning solutions for diverse industries. Our robust jacks reliably move and accurately position loads up to 100 t. We configures jacks with components such as motors, worm gearbox motor reducers, shafting, coupling, and motion control devices to create complete multi-jack systems.


NMRV Worm Gearbox Motor Reducer offer light weight, cost effective operation and superior performance for a variety of industrial applications. A worm gear reducer motor is combined with a worm gear screw jack as a complete motor reducer worm gear screw jack, which has lower lifting speed and larger torque for use. They are available in both NEMA and IEC motor flange (motor adapters) configurations for motor flexibility.
