A lead screw that converts rotational motion to linear motion sits inside the motor body for a compact footprint. Add a driver and controller to these actuators to repeatedly position loads with speed and precision. Choose from our selection of electric screw jacks, including Acme screw jacks, stepper motors, and more. In stock and ready to ship. Screw Jacks, also known as mechanical actuators, are used to lift, position — such as push, pull, tilt, or roll — and support all types of loads. Mechanical screw jacks are used in machines and equipment to convert rotary motion into linear motion or force.
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. 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, also known as screw lead, is the.
Machine Screw Jacks having gear ratios between 20:1 and 32:1, are self-locking and, in the absence of vibration, will hold loads without backdriving. All other ratios may require a brake to prevent backdriving. All Ball Screw Jacks can backdrive and require some means of holding the load, such as a brake on the motor.
A jackscrew, or screw jack, is a type of jack that is operated by turning a leadscrew. It is commonly used to lift moderately and heavy weights, such as vehicles; to raise and lower the horizontal stabilizers of aircraft; and as adjustable supports for heavy loads, such as the foundations of houses. 
Jackscrews (also referred to as jack screws or screw jacks) are among several different kinds of linear motion actuators most often used for lifting or moving loads. They can also be used in any application needing linear motion, or where pushing or pulling along a linear axis is needed. Other common mechanical actuators include lead, ball, and.
ActionJac™ Worm Gear Screw Jack systems are ruggedly designed and produced in standard models with load handling capacities from 1/4 ton to 100 tons. Metric capacities are also available from 5 kN to 200 kN. No "standard" travel lengths (built to specification). Ductile iron housings proportioned to support the rated capacity of the unit.
Screw Jacks and Environmental Applications. Nook screw jacks offer the ability to lift, position, hold and support loads in a variety of industrial applications. These jacks will provide excellent performance and reliability in the average indoor industrial facility with a dry environment and an operating temperature of 32oF (0oC) - 180oF (82oC).
From one compact system, transmit linear or rotary motion or both at once (sometimes called spiral motion). Because of these different motions, these ball screw/splines and bearings create efficient, fluid movements in complex automated applications, such as pick-and-place robots. Choose from our selection of jack screws, including lead screws.
If the required screw jack maximum horsepower is exceeded: Use a larger screw jack size. Consider a Ball Screw Jack (as a Machine Screw Jack alternative) Decrease the input speed. Use a right angle reducer. 4. Column Strength. Column Strength is the ability of the lift shaft to hold compressive loads without buckling.
