Professional Applications & Engineering Value

This 304 Stainless Steel ACME lead screw delivers critical performance advantages in precision motion control systems. The left-hand thread direction provides essential counter-rotation capability for synchronized multi-axis systems and specialized machinery where standard right-hand threads would be impractical. Engineered with Class 2C thread fit and single-start configuration, this component minimizes backlash while maintaining smooth operation under substantial loads. The fully threaded design across the entire 3-foot length offers installation versatility in CNC equipment, industrial automation, and precision positioning systems. With its ±0.009" per foot accuracy, this lead screw ensures repeatable positioning in medical devices, packaging machinery, and automated assembly lines where dimensional stability is paramount. The combination of 72,000 psi tensile strength and corrosion-resistant 304 stainless steel makes it suitable for both standard industrial environments and applications requiring frequent washdowns or exposure to chemicals.

Specification Summary & Compliance
