S-3405N058 1"-4 x 2 ft. Ball Screws and Nuts

Key Features & Benefits at a Glance

• Exceptional positioning accuracy with ±0.004" per foot travel tolerance for reliable, repeatable linear motion in automated systems.
• Superior load-bearing capacity from 85,000 psi tensile strength, ensuring long-term performance under high-stress industrial applications.
• Extended service life in harsh conditions due to hardened alloy steel construction and Rockwell C56 hardness, resistant to wear and deformation.
• Wide operational temperature range from -40°F to 300°F, maintaining precision in both freezing and high-heat environments.
• Optimized efficiency with rolled thread fabrication, providing smoother operation and higher fatigue resistance compared to cut threads.
• Left-hand threading capability for specialized machinery requiring reverse linear motion or counter-rotational setups.
• Fully threaded 2 ft length design offers flexible mounting and integration into various linear motion systems.

Professional Applications & Engineering Value

This left hand ball screw is engineered to solve critical challenges in precision automation and motion control systems. The hardened alloy steel construction and rolled thread fabrication significantly reduce backlash and wear, addressing common failure points in high-cycle applications like CNC machinery, robotic actuators, and precision assembly equipment. With a consistent 0.25" travel distance per turn and tight ±0.004" per foot accuracy, it ensures repeatable positioning where minute deviations cause costly errors. The fully threaded design and left-hand thread direction make it ideal for creating synchronized counter-movement or space-constrained installations where standard right-hand screws are impractical. Its robust 85,000 psi tensile strength and wide temperature tolerance provide reliable performance in demanding industrial environments, from automotive manufacturing to aerospace testing facilities.

Specification Summary & Compliance

This 1"-4 ball screw features precision rolled threads with Class 2A thread accuracy and a left-hand thread direction. Manufactured from hardened alloy steel to Rockwell C56 hardness, it complies with industry-standard linear motion specifications. The component meets material and performance requirements consistent with ASME standards for precision power transmission components and is manufactured in compliance with RoHS and REACH environmental directives.
