Machine Screw Jack - Inverted Translating Keyed
1/4 Ton to 75 Ton
Prevents rotation of the lift shaft with a square guide attached to the screw translating inside a square stem cover attached to the jack. The square stem tube is supplied with lube fittings.
Used when reversible load conditions require precision positioning control. Adjustable models reduce backlash to approximately 0.003".
The lash between the drive sleeve thread and the lift screw thread is controlled by adjusting the top cover. This changes the relative distance between the drive sleeves to compensate for lash. The drive sleeve is split, resulting in reduced life. Machine Screw Jack Home Page
