Professional Applications & Engineering Value
This self-reversing lead screw is engineered for precision motion control in demanding applications such as automated machinery, positioning systems, and medical devices. The combination of 1144 carbon steel for the screw and aluminum for the nut delivers an optimal balance of strength and weight efficiency. The diamond thread type ensures smooth, low-friction operation, minimizing backlash and enhancing positional accuracy. With a travel distance of 0.75" per turn and tight ±0.007" accuracy, it solves critical engineering challenges like space constraints and repetitive motion reliability. Its ability to operate in a broad temperature range from -50°F to 350°F makes it suitable for both industrial and specialized environments, providing consistent performance where thermal stability is crucial.
Specification Summary & Compliance
This lead screw assembly features a 3/4" diameter with a partially threaded design and 8 13/16" travel length. It adheres to standard inch measurements and offers precise Class 2A thread tolerances. The diamond thread form and single thread start ensure compatibility with common motion systems. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming adherence to environmental and safety regulations for industrial use.
