Acme Screw Jacks
 |
Top View |
Broad, strong Acme threads make these screw jacks better than ball screw jacks for heavy loads, intermittent positioning applications, and where vibration is present. Screw jacks come assembled, threaded, and ready for hookup. Connect a motor or hand-crank shaft to the screw jack shaft to lift, hold, position, and level loads.
Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a load moves with one revolution of the shaft.

Acme Screw Jacks with Mounting Plate
|
Top View |
The mounting plate provides a flat surface for supporting loads. Broad, strong Acme lead screw threads make these screw jacks good for heavy loads, intermittent positioning applications, and where vibration is present. Connect a motor or hand-crank shaft to the screw jack shaft to lift, hold, position, and level loads. Screw jacks come assembled, threaded, and ready for hookup.
Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a load moves with one revolution of the shaft.
