S-6350K131 3/4"-10 x 6 ft. Ultra-Precision Lead Screws and Nuts

Key Features & Benefits at a Glance

• Exceptional positioning accuracy with ±0.0006" per inch travel tolerance for highly repeatable motion control in precision machinery.
• Superior corrosion resistance and machinability from 303 Stainless Steel construction, ensuring long-term reliability in harsh industrial environments.
• High load-bearing capacity with a 90,000 psi tensile strength and Brinell 160 hardness, providing durability under significant mechanical stress.
• Smooth, efficient power transmission due to the rounded Acme thread profile, which reduces friction and wear compared to square threads.
• Consistent, predictable linear motion with a 0.1" travel distance per turn and a single thread start, simplifying system design and control.
• Full 6-foot length and continuous threading offering design flexibility for long-travel applications without the need for couplings.
• Compliance with major environmental and safety standards including RoHS 3 and REACH, ensuring suitability for global markets and sensitive applications.

Professional Applications & Engineering Value

This 3/4"-10 Rounded Acme Lead Screw is engineered for ultra-precision motion control systems where accuracy and reliability are non-negotiable. Manufactured from 303 Stainless Steel, it provides excellent corrosion resistance and mechanical properties, making it ideal for CNC machinery, medical devices, optical positioning equipment, and automated assembly lines. The fully threaded design and right-hand thread direction ensure consistent force transmission across the entire 6-foot length, while the rounded Acme thread type minimizes backlash and distributes load evenly. This combination of high tensile strength (90,000 psi) and precise ±0.0006" per inch accuracy directly addresses engineering challenges such as positional drift, component wear, and maintenance frequency, delivering long-term operational stability and reduced total cost of ownership in demanding industrial applications.
