S-6350K128 1/4"-20 x 6 ft. Fast-Travel Ultra-Precision Lead Screws and Nuts

Key Features & Benefits at a Glance

• Ultra-precise positioning with ±0.0006" travel accuracy per inch for reliable, repeatable motion control in demanding applications.
• Fast travel speed achieved through a 2:1 speed ratio and dual thread starts, doubling linear movement per revolution for increased operational efficiency.
• Exceptional durability from 303 Stainless Steel construction, offering excellent corrosion resistance and a high 90,000 psi tensile strength for long service life.
• Reduced wear and smooth operation thanks to the rounded Acme thread profile, which minimizes friction and extends component lifespan in high-cycle use.
• Robust performance under load supported by a Brinell 160 hardness, ensuring the screw maintains dimensional stability and resists deformation.
• Full 6-foot length and complete threading provide design flexibility and continuous drive capability for a wide range of industrial setups.
• Global compliance assurance with RoHS 3 and REACH standards, guaranteeing environmental safety and unrestricted use in regulated markets.

Professional Applications & Engineering Value

This ultra-precision lead screw is engineered to solve critical challenges in motion control systems where speed, accuracy, and reliability are paramount. The 303 Stainless Steel material provides superior corrosion resistance, making it ideal for harsh environments like medical devices, packaging machinery, and laboratory automation. The rounded Acme thread design significantly reduces friction compared to square threads, enabling smoother operation and lower wear over time. With a 0.1" travel per turn and ±0.0006" accuracy, it ensures precise linear positioning in applications such as CNC stages, 3D printers, and optical equipment. The 2:1 speed ratio and dual thread starts allow for rapid traversal without sacrificing control, enhancing throughput in fast-travel industrial applications.
