Nook Industries‘ line of bevel gear screw jack systems, under the ActionJac brand, is available in many configurations.  Available in machine and ball models, all bevel gear screw jacks offer load-handling capabilities from 12.3 kN to 117 kN. They may be used individually or in multiple arrangements, and because there are no standard travel lengths, each one is built to specification.

Machine screw jacks incorporate the use of a trapezoidal acme screw that conforms to DIN 103 standard with a low backlash between nut and screw. For applications requiring smoother motion, higher speeds or less torque, ball screw jacks are available.

Additionally, ActionJac bevel gear screws can be arranged in three jack configurations: translating, rotating and keyed. This allows the load to be moved in different ways along the lift shaft, offering further options for customers.
