Professional Applications & Engineering Value
This ACME lead screw delivers critical performance in precision motion control systems where reliability and accuracy are paramount. Engineered from ASTM Grade B7 alloy steel, it provides the necessary strength and hardness (Rockwell C35) to withstand continuous operation in industrial machinery, CNC equipment, and automated positioning systems. The 1 1/4"-4 ACME thread configuration with 0.25" travel per turn offers predictable linear motion, while the Class 2G thread fit ensures minimal play and consistent performance under varying loads. The fully threaded, 12-inch length design maximizes utility in applications requiring long travel distances, making it ideal for material handling systems, precision actuators, and industrial automation where motion control accuracy directly impacts operational efficiency and product quality.
Specification Summary & Compliance
This ACME lead screw features precise Class 2G thread fit tolerances with 1 1/4"-4 thread size and single thread start configuration. Manufactured to ASTM A193 specifications using ASTM Grade B7 alloy steel with 125,000 psi tensile strength and Rockwell C35 hardness. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring suitability for global industrial markets and regulatory requirements.
