• Smooth, predictable linear motion from the single-start, fully-threaded Acme design, ensuring consistent 0.2" travel per turn.
• Broad compatibility and easy assembly with a standard Class 2C thread fit for simplified integration into existing systems.
• Compliance with environmental regulations as a RoHS 3 compliant component, suitable for global markets.
• Optimized for high-load, low-speed applications with a right-hand thread and 1:1 speed ratio for precise power transmission.

Professional Applications & Engineering Value

This 1"-5 ACME lead screw is engineered to solve core challenges in industrial automation and motion control. The hardened 4140 alloy steel construction and Brinell 271 hardness provide exceptional resistance to wear and deformation under heavy loads, making it ideal for CNC machinery, lifting equipment, and precision positioning tables. The fully threaded, right-hand Acme thread delivers a consistent 0.2" of travel per revolution, ensuring precise linear movement without backlash. The Black-Oxide finish adds a layer of corrosion resistance, crucial for maintaining performance in harsh industrial environments. This combination of high tensile strength and rigorous accuracy (±0.009" per ft.) makes it a reliable component for applications where failure is not an option, directly addressing the need for durability and precision in motion control systems.

Specification Summary & Compliance
