High Speed Lead Screws Products & Suppliers

A leadscrew (or lead screw), also known as a power screw or translation screw, is a screw used as a linkage in a machine, to translate turning motion into linear motion. Because of the large area of sliding contact between their male and female members, screw threads have larger frictional energy losses compared to other linkages. They are not typically used to carry high power, but more for in… Web10 dec. 2024 · For achieving higher speeds, with lower RPMs, we typically recommend high-helix lead screws. One potential downside for some applications is the backlash that is present in lead screw nuts. This occurs because lead screw nuts operate under a sliding vs rolling condition where there needs to be extra tolerances to allow for smooth motion .
