Professional Applications & Engineering Value
This ACME lead screw delivers superior performance in demanding motion control applications where precision and reliability are critical. Manufactured from ASTM Grade B7 alloy steel, it provides exceptional strength-to-weight ratio while maintaining dimensional stability under heavy loads. The fully threaded design with right-hand ACME threading ensures consistent force transmission in industrial automation, CNC machinery, and lifting systems. The Class 2G thread fit offers optimal clearance for smooth operation while minimizing play, making it ideal for applications requiring repeatable positioning accuracy. With its 0.25" travel per turn, this screw converts rotational motion to linear movement with predictable efficiency, reducing system calibration time and maintenance requirements in production environments.
Specification Summary & Compliance
This ACME lead screw features 1 1/4"-4 thread size with Class 2G thread fit per industry standards. Manufacturing complies with ASTM A193 specification for high-temperature service, while material properties meet ASTM Grade B7 requirements with 125,000 psi tensile strength and Rockwell C35 hardness. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant for environmental safety standards.
