    Low-friction ball bearings allow these screw jacks to use half the power required by an Acme screw jack to lift the same load. Typically used as actuators, they run at higher speeds than Acme screw jacks. They 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.
