Acme Screw Jacks
Broad, strong Acme threads make these screw jacks much better than ball screw jacks for heavy loads, intermittent positioning applications, and where vibration is present. Screw jacks arrive assembled, threaded, and prepared for hookup.Connect a motor or hand-crank shaft to the screw jack shaft to lift, hold,placement, and level loads.
Travel distance per turn, also referred to as screw lead, is the distance a load moves with a single revolution of the shaft.
Acme Screw Jacks with Mounting Plate
The mounting plate offers a flat work surface for supporting loads. Wide, strong Acme business lead screw threads make these screw jacks good for large loads, intermittent positioning applications, and where vibration exists. Connect a motor or hand-crank shaft to the screw jack shaft to lift,hold, placement, and level loads. Screw jacks come assembled, threaded, and prepared for hookup.
Travel distance per convert, also referred to as screw lead, may be the distance a load moves with 1 revolution of the shaft.

Ball Screw Jacks
Low-friction ball bearings allow these screw jacks to make use of half the power required by an Acme screw jack to lift the same load. Typically used as actuators, they operate at higher speeds than Acme screw jacks. They arrive assembled, threaded, and ready for hookup. Connect a engine or hand-crank shaft to the screw jack shaft to lift, hold, position, and level loads.
Travel distance per convert, also referred to as screw lead, may be the distance lots moves with a single revolution of the shaft.
