Professional Applications & Engineering Value
This precision ACME lead screw with left-hand thread configuration solves critical reverse motion challenges in industrial automation, CNC machinery, and positioning systems. The 1018 carbon steel construction combined with Brinell 126 hardness provides exceptional wear resistance for high-cycle applications. The fully threaded design and Class 2C fit ensure consistent performance with matching nuts, while the 0.25" travel per turn delivers precise linear motion control. Engineered for demanding environments, this 2"-4 ACME lead screw maintains dimensional stability under load, making it ideal for material handling equipment, printing machinery, and automated assembly systems where reverse-direction operation is required.
Specification Summary & Compliance
This precision lead screw features 2"-4 ACME left-hand threads with Class 2C fit per inch system standards, ensuring proper clearance for smooth operation. The manufacturing maintains ±0.009" per foot accuracy for travel distance, with single-start threading providing consistent 0.25" travel per turn. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting international standards for industrial use while delivering reliable performance in demanding applications.
