S-3405N122 1"-4 x 8 ft. Fast-Travel Ball Screws and Nuts

Key Features & Benefits at a Glance

• Enhanced Load Capacity & Durability: Hardened alloy steel construction with 85,000 psi tensile strength and Rockwell C56 hardness ensures superior resistance to wear and deformation under heavy loads.
• Exceptional Positioning Precision: Delivers a tight ±0.004" per foot travel accuracy, guaranteeing repeatable and reliable performance in high-precision automation and machinery.
• Rapid Motion & High Efficiency: The 4-start thread and 1" travel distance per turn enable fast-travel applications, significantly reducing cycle times and increasing throughput.
• Superior Thread Integrity & Long Service Life: Rolled thread fabrication creates a stronger, more fatigue-resistant thread profile compared to cut threads, extending the component's operational lifespan.
• Broad Operational Temperature Resilience: Withstands a wide temperature range from -40° to 300° F, ensuring stable performance in demanding or environmentally variable industrial settings.
• Optimized for High-Performance Systems: The fully threaded, 8 ft length and right-hand direction make it an ideal, ready-to-integrate component for long-stroke, fast-travel ball screw assemblies.

Professional Applications & Engineering Value

This high-precision ball screw is engineered to solve critical challenges in automation, CNC machinery, and high-speed linear motion systems. The core value lies in its hardened alloy steel material and rolled thread fabrication, which work in concert to combat common failure points like thread wear, backlash, and loss of positional accuracy under continuous operation. The 4-start thread design is pivotal for fast-travel applications, allowing for significantly higher linear speed without increasing the rotational speed of the motor, thereby reducing inertia and wear on drives. This makes it an indispensable component for engineers designing systems where speed, precision, and durability are non-negotiable, such as in precision gantry systems, industrial robotics, and high-performance material handling equipment. Its robust construction directly addresses the engineering need for components that deliver long-term reliability and minimal maintenance in demanding industrial environments.
