Key Features & Benefits at a Glance
- Precision motion control with 0.25" travel per turn for accurate linear positioning in automated systems
- Exceptional durability from Grade 2 carbon steel construction providing 53,000 psi tensile strength for heavy-duty applications
- Reliable thread engagement with Class 2G thread fit ensuring consistent performance and reduced wear over time
- Left-hand thread design enabling specialized applications requiring reverse-direction movement or counter-rotation safety
- Industrial-grade hardness at Rockwell B61 for superior wear resistance in high-cycle operations
- Full-length threading allowing maximum flexibility in nut positioning along the entire 6-foot length
- Regulatory compliance meeting ASTM A108, RoHS 3, and REACH standards for global industrial acceptance
Professional Applications & Engineering Value
This left-hand Acme lead screw delivers critical engineering value in applications requiring precise reverse-direction linear motion, such as clamping systems, precision machining equipment, and specialized automation where standard right-hand threads would be unsuitable. The Grade 2 carbon steel construction combined with the Acme thread profile provides optimal strength-to-weight ratio while maintaining the dimensional stability needed for repetitive positioning tasks. The Class 2G thread fit ensures smooth operation with minimal backlash, significantly reducing maintenance intervals in industrial environments. With its 0.25" travel per turn, this screw offers predictable movement critical for synchronization in multi-axis systems, while the fully threaded 6-foot length accommodates various mounting configurations without compromising performance.
Specification Summary & Compliance
This 1 1/4"-4 Acme lead screw maintains Class 2G thread fit tolerances as specified by ANSI/ASME B1.5 standards, ensuring precise dimensional accuracy for industrial applications. Manufactured in compliance with ASTM A108 specifications for material consistency and performance reliability. The product fully meets RoHS 3 (2015/863/EU) compliance for restricted substances and REACH (EC 1907/2006) regulations regarding chemical safety, making it suitable for global industrial markets and environmentally conscious operations.
