The ActionJac line of worm-gear screw jacks consists of machinescrew, ball-screw, stainless-steel, metric, and trapezoidal screw jack options. Used individually or in multiple arrangements, each jack is built to specification with customized travel lengths and load-handling capacities ranging from ¼ to 100 tons.

Each model’s worm-gear-set arrangement uses an alloy-steel worm, which drives a high-strength bronze worm gear (drive sleeve). The worm shaft is supported on antifriction tapered roller bearings with external seals to prevent loss of lubrication. Machine-screw jacks feature a lifting shaft made of alloy steel with a minimum tensile strength of 95,000 psi. Lead accuracy is approximately 0.004 in./ft.

Ball-screw jacks feature a high-efficiency ball screw and nut that reduces the required input torque to about one-third the torque required for machine-screw jacks. 300 Series Stainless-steel screw jack are for environments where corrosion resistance is essential. Stainless-steel lifting threads are precision formed to Class 2-C (centralizing) thread profiles.
