One of the benefits of screw jacks is that the load is generally self-locking; this means that the motion can't be back-driven by the weight of the load. This makes them a very safe option, and the load will maintain that position even when the motion force is removed, no matter ...
Short force screws, such as those in jacks, work by compression; they are checked for strength and buckling during their design and manufacture. Long force screws work by tension and are tested for tensile strength. Micrometer screws have a precision thread with a small pitch; they are used ...

A ceramic shell (1) houses a metallic linkage sleeve (2) which is provided with two tapped holes to accommodate fixing screws (4,5). One of the screws (4) clamps the lamp terminal pin socket jacks (3), which are introduced into one end of the sleeve, and the other clamps the bare...
There are 3 main types of screw jacks: machine/worm gear screw jacks, ball screw jacks, and bevel gear jacks. Within these, there are 3 subcategories related to the mode of operation: Translating, Keyed, and Rotating/Traveling nut. The advantages and disadvantages of each type are given belo...
