Lead Screws

Lead screws often referred to as power screws are very similar to traditional screws but without a head. They are commonly made from carbon steel, stainless steel or aluminium. Lead screws are used in motion control to translate turning or rotating movements into a linear motion.

How do lead screws work?

Lead screws enable smooth, precise, movement and are often preloaded with an axial load that enables consistent contact between the nuts and screw filets. The screw threads require a large area of sliding contact between the external male threads and internal female threads. As the lead screw turns or rotates on a machine, the attached threaded hole from the nut moves along the screw in a linear motion.

These nuts are typically made from plastic or bronze and sometimes the addition of a PTFE type coating protects the screws and provides additional lubrication for the nut.

Lead screws are available in various diameters and lengths with a range of different pitches or lead dependent upon your application. These screws are widely used in lab testing equipment such as sampling and scanning as well as within the biomedical industry, clinical and hospital equipment.
