Professional Applications & Engineering Value

This precision ACME lead screw is engineered to solve core challenges in motion control systems, such as backlash and positioning inaccuracy. Manufactured from durable 304 Stainless Steel, it resists corrosion in humid or washdown environments, common in packaging, CNC positioning, and medical equipment. The ACME thread form and Class 2C thread fit provide a balance of strength and clearance, reducing binding and wear in applications with slight misalignments. With its specified ±0.009" per foot travel accuracy and consistent 0.05" travel per turn, this fully threaded component delivers predictable linear motion, enhancing the reliability of automated actuators, 3D printers, and precision lifting mechanisms.

Specification Summary & Compliance

This lead screw adheres to inch system standards with a 1/4"-20 ACME thread size and a Class 2C thread fit for general purpose applications. The manufacturing ensures a consistent travel distance per turn of 0.05" with an accuracy of ±0.009" per foot. The component is fully threaded with a right-hand thread direction and a single thread start. It is confirmed to be RoHS 3 (2015/863/EU) Compliant, meeting stringent environmental directives for hazardous substance restrictions.
