Professional Applications & Engineering Value

This high-precision ACME lead screw delivers critical engineering value in applications requiring reverse or counter-rotational motion control. The 304 Stainless Steel construction provides excellent corrosion resistance for food processing, marine, and chemical environments where moisture resistance is essential. The left-hand threading enables specialized mechanical configurations in clamping systems, precision valves, and automated machinery where standard right-hand threads would be impractical. With ±0.009" per foot accuracy and 72,000 psi tensile strength, this component maintains positional integrity under substantial loads, preventing system drift and reducing maintenance requirements in CNC equipment, linear actuators, and industrial automation systems.

Specification Summary & Compliance

This 1 1/2"-4 ACME lead screw features Class 2C thread fit per inch system standards, ensuring proper clearance for smooth operation. The component maintains 0.25" travel distance per turn with single-start threading and measures 3 feet in length. Manufacturing complies with RoHS 3 (2015/863/EU) environmental directives, confirming restriction of hazardous substances. The Brinell 150 hardness and precise ACME thread profile guarantee consistent performance in mechanical power transmission applications requiring reliable, long-term operation.
