Professional Applications & Engineering Value
This ACME lead screw is engineered to address critical challenges in industrial motion control, such as precise linear actuation and heavy-load positioning. The ASTM Grade B7 alloy steel construction provides superior strength and fatigue resistance, ideal for applications in CNC machinery, lifting equipment, and automated assembly lines where reliability is paramount. The left-hand thread and Class 2G fit ensure stable performance in systems requiring reverse or counter-rotational movements, reducing the risk of thread stripping under dynamic loads. With its fully threaded design and consistent 0.2" travel per turn, it delivers smooth, predictable motion, minimizing maintenance downtime and enhancing operational efficiency in demanding environments like manufacturing and material handling.
Specification Summary & Compliance
This product adheres to Class 2G thread fit tolerances for reliable assembly and performance. It conforms to ASTM A193 specifications for material and manufacturing standards, with a thread size of 1 1/8"-5 ACME. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) ensures environmental safety and regulatory acceptance in global markets.
