S-3405N061 1"-4 x 6 ft. Ball Screws and Nuts

Key Features & Benefits at a Glance

• Exceptional Positioning Accuracy: Maintains ±0.004" per foot travel accuracy for highly repeatable motion control in automated systems.
• Superior Load-Bearing Capacity: With a tensile strength of 85,000 PSI, this screw reliably handles high thrust loads in demanding applications.
• Enhanced Wear Resistance & Longevity: The hardened Alloy Steel construction and Rockwell C56 hardness provide excellent durability, reducing maintenance frequency.
• Optimized for Reverse-Motion Systems: The Left-Hand Thread direction is ideal for applications requiring counter-rotational or specific mechanical synchronization.
• Consistent & Efficient Power Transmission: The 0.25" travel distance per turn and single-start thread ensure predictable and smooth linear motion.
• Robust Thread Integrity: Rolled thread fabrication creates a stronger, more fatigue-resistant thread profile compared to cut threads.
• Broad Operational Temperature Range: Performs reliably in environments from -40° to 300° F, suitable for various industrial settings.

Professional Applications & Engineering Value

This 1"-4 Left Hand Ball Screw is engineered to solve critical challenges in high-precision automation and motion control. Its hardened alloy steel construction and rolled thread fabrication directly address the need for components that can withstand continuous high-load cycles without premature wear or failure. The left-hand threading is essential for complex machinery requiring mirrored or opposing linear motion, such as in certain types of CNC equipment, precision gantry systems, and custom automation cells. The combination of a 0.25" travel per turn and exceptional ±0.004" per ft. accuracy ensures that systems achieve precise positioning and repeatability, which is paramount in manufacturing, aerospace, and robotics applications where errors are not an option. This component delivers reliable engineering value by increasing machine uptime and output quality.

Specification Summary & Compliance
