Professional Applications & Engineering Value
This ultra-precision lead screw delivers critical performance where minute positioning errors are unacceptable. Manufactured from 303 Stainless Steel, it resists corrosion in medical, aerospace, and laboratory equipment while maintaining dimensional stability. The rounded Acme thread profile provides smoother engagement than square threads, distributing load evenly to extend service life in high-cycle applications. With ±0.0006" per inch accuracy, it eliminates cumulative error in long-travel systems like CNC stages and optical positioning equipment. The fully threaded 18-inch length offers installation flexibility while the single-start design ensures predictable linear advancement per revolution for synchronized motion systems.
Specification Summary & Compliance
This precision component features 9/64"-20.8 rounded Acme threading with right-hand direction and fully threaded 18-inch length. Manufacturing adheres to ultra-precision standards with travel accuracy maintained within ±0.0006" per inch. Mechanical properties include 90,000 psi tensile strength and Brinell 160 hardness. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant regarding SVHC substances as of June 2022, ensuring environmental regulatory adherence for global distribution.
