Screw jacks, also commonly referred to as jack screws, use a long threaded rod to position a matching nut at any position along its length. In a screw jack, forces acting on the nut along the length of the rod do not appreciably affect the rotation of the rod. In general, screw jacks are not considered self-locking. They are designed for both tensile and compressive loads and can work in any orientation or mounting position.
There are many variations of screw jacks. They are available in a wide range of speeds, load capabilities, end fittings, and mounting arrangements. They can also be synchronized with other jack screws. Screw jacks commonly use an acme along the threaded rod, which gives the screw strength and resistance to the large loads imposed on most screw jacks. At the same time, the screw is not severely weakened by wear over many rotations. Grease is the most common lubricant used for screw jacks.
Screw jacks are widely used in many common applications. With the ability to push, pull, lift, lower and position loads of many sizes, they serve many useful purposes. They can operate in very harsh conditions, including nuclear applications. Other typical uses include car-locks, railway applications, securing connectors in computer and other electronic equipment, linear actuators, and many more.
