Professional Applications & Engineering Value
This ACME lead screw is engineered to address critical challenges in industrial motion control, such as maintaining precision under heavy loads and reducing backlash in automated systems. The ASTM Grade B7 alloy steel construction provides high tensile strength and hardness (Rockwell C35), making it ideal for applications like CNC machinery, lifting equipment, and valve actuators where durability and repeatability are paramount. The fully threaded design with 2 1/2"-4 ACME threads ensures efficient power transmission and minimal deflection, while the right-hand thread direction and Class 2G fit offer reliable performance in demanding environments, reducing maintenance needs and downtime.
Specification Summary & Compliance
This lead screw adheres to Class 2G thread fit tolerances for consistent engagement and meets ASTM A193 specifications for high-strength components. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring environmental safety and regulatory acceptance. Manufactured in the inch system with a single-start thread and 0.25" travel per turn, it guarantees precise dimensional accuracy for seamless integration into industrial systems.
