Professional Applications & Engineering Value
This 3/8-8 ACME lead screw is engineered to solve critical challenges in precision motion control systems, such as CNC machinery, linear actuators, and material handling equipment. Constructed from ASTM Grade B7 alloy steel, it resists wear and deformation under continuous operation, while the fully threaded design and Class 2G thread fit minimize backlash for smooth, repeatable movements. The right-hand ACME thread type and single start provide reliable force transmission, making it ideal for applications requiring exact travel per turn—like packaging, automation, and positioning systems—where durability and accuracy are paramount. Its compliance with industry standards ensures seamless integration and long-term reliability in harsh industrial environments.
Specification Summary & Compliance
This lead screw adheres to Class 2G thread fit tolerances per inch system standards, with threading conforming to ACME specifications (3/8"-8 size, right-hand direction). It meets ASTM A193 manufacturing requirements for material and strength, and is verified as RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, supporting safe and sustainable use in global markets.
