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.

A bevel gearbox is a device used to transmit and/or split/distribute the power of a singular rotating mechanical drive shaft through a defined angle, typically 90°. Though most bevel gearboxes operate at 90° angles other angles are also available, both acute (less than 90°) and obtuse (greater than 90°).

A linear actuator is a device or machine that converts rotational motion into linear motion and linear movement (in a straight line). This can be done through electric AC and DC motors, or the movement could be powered by hydraulics and pneumatics.

Screw lead is the linear distance moved by the nut in one revolution (360°) of the nut or the shaft. The smaller the lead, the tighter the thread, resulting in more precise linear motion. The pitch is the distance between two adjacent crests or troughs measured parallel to the axis of rotation.

A roller screw, also known as a planetary roller screw or satellite roller screw, is a low-friction precision screw-type actuator, a mechanical device for converting rotational motion to linear motion, or vice versa.

A screw jack system is where more than one screw jack is operated in unison to achieve a linear movement. The screw jack system arrangement is also commonly referred to as a “jacking system”. The ability to mechanically link multiple screw jacks together so that they move in unison is one of their greatest advantages.
