Ball Screw Jack nook industries 

Standard model capacities from 1/4 ton to 100 tons. Metric capacities from 5 kN to 200 kN.

ActionJac™ Worm Gear Ball Screw Jacks use a ball screw and nut made from hardened alloy steel with hardened bearing balls carrying the load between nut and screw. This rolling action reduces friction between the nut and the screw permitting smooth and efficient movement of the load. Because of the greater efficiency and rolling action, the ball screw can operate at higher speeds and increased duty cycle when compared with the Machine Screw Jack.

Improved speed, force, duty cycle, acceleration
Longer life cycle (low friction)
Requires less motor power
Greater positioning accuracy
Higher static load and lower dynamic load
