- Precision Movement Control - 0.2" travel per turn provides consistent, predictable linear motion for accurate positioning.
- Reliable Reverse Motion Capability - Left-hand threading offers specialized solutions for counter-clockwise driven systems and safety applications.
- Optimized Thread Engagement - Class 2G thread fit ensures smooth operation with minimal backlash in mating components.
- Full-Length Threading Versatility - Fully threaded design allows for adjustable positioning along the entire 6-foot length.
- Industry-Compliant Material Quality - ASTM Grade B7 alloy steel construction meets rigorous industrial standards for reliability.
Professional Applications & Engineering Value
This 1 1/4"-5 Left Hand Acme Lead Screw delivers critical performance in precision motion control systems where reliability and strength are paramount. Engineered from ASTM Grade B7 alloy steel, it solves common industrial challenges like thread wear and deformation under heavy loads. The fully threaded Acme design with Class 2G thread fit ensures smooth, predictable movement in applications requiring reverse motion capability, such as clamping systems, lifting mechanisms, and safety shut-off devices. The left-hand threading provides specialized solutions where standard right-hand threads would be impractical, while the 0.2" travel per turn offers precise control in automated positioning systems, CNC machinery, and industrial actuators.
Specification Summary & Compliance
This lead screw features Class 2G thread fit with 1 1/4"-5 Acme threading and left-hand direction. Manufactured to ASTM A193 specifications using ASTM Grade B7 alloy steel, it delivers 125,000 psi tensile strength and Rockwell C35 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use in regulated industrial environments worldwide.
