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.
Trapezpodal screw jack best for slower movement and low to moderate duty cycles .most machine screw jacks are inherently
self-locking in the absence of vibration . A brake motor is usually not required to hold position on self locking jacks
.Anti-backlash advices can be specified to limit backlash in reversing loads . Stainless steel , metric and motorized jack models
are available with machine screws . Adaptable for wash down applications.
