Professional Applications & Engineering Value
This 3/4"-6 ACME lead screw is engineered for demanding motion control applications in industrial automation, CNC machinery, and linear actuators. The Grade 2 carbon steel construction, combined with ACME threads, provides high torque transmission efficiency and resists backlash, addressing common issues of positional inaccuracy and mechanical wear. The fully threaded, right-hand design ensures consistent force distribution and easy integration with standard nuts, while the Class 2G thread fit minimizes friction for smoother operation. Its 4 ft. length and 0.167" travel per turn make it ideal for long-stroke applications requiring precise linear movement, enhancing productivity and reducing maintenance in harsh industrial settings.
Specification Summary & Compliance
This lead screw adheres to Class 2G thread fit tolerances for reliable engagement and is manufactured in compliance with ASTM A108 standards. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free of hazardous substances. The ACME thread type and right-hand direction conform to industry norms, while the specified tensile strength and hardness validate its performance for precision engineering applications.
