Self Leveling Programmable System, when used with a suitable assembly jig, assures close-tolerance repeatability despite subtle out-of-level changes caused by heavy workpiece loading/unloading, vibration, sound resonance‹even earthquake activity that disturbs a normal jig's tool-to-workpiece positioning.

Ideal wherever very tight tolerances are critical... (read more)

NOOK Industries ActionJac™ Screw Jacks are a worm gear driven mechanical actuator with load handling capacities from 1/4 ton to 100 ton and 5kN to 200kN. ActionJac Screw Jacks are available in ball screw and acme screw models with nine different configurations. (read more)

Joyce Ball Screw Jacks feature a ball nut with integral ball bearings that recirculate along the surface of the ball screw. The significantly reduced friction between the ball nut and screw results in greater efficiency, with up to 2/3 less input torque required to move the load than a similarly rated machine screw jack.
