Manufacturer supplier exporter of the screw jack.

The ball screw jack is designed to have capacities ranging from one to 100 tons. Optimized and efficient for higher speed, greater duty cycle, and quieter operation.

◆ Option: anti-rotation, greater pitch options available
◆ The translational (traveling screw) and rotational (traveling nuts) configurations
◆ Forces are applied and moved more effectively than other lead screw mechanical actuators
◆ No self-locking! Because there isn’t any friction an electric brake is needed.
◆ The best materials: Durable iron ductile housing high-performance ball screw ball thrust bearings for robust reliability, and high-strength bronze worm gear

We can assure you of top quality, timely delivery, and cost controllable with low risks.
