High-Precision Custom CNC Ball Screws: SFU1605 40mm GCr15 Steel Ball Screws for Reliable Motion Control

If you’re looking for durable, high-precision motion solutions for your CNC machinery, automated equipment, or industrial systems, custom ball screws are one of the most critical components to consider. At Shuntai, we specialize in manufacturing precision ball screws designed to deliver consistent performance, long service life, and reliable load-bearing capacity for even the most demanding applications.

What Makes the SFU1605 40mm Ball Screw Stand Out?

Our SFU1605 40mm ball screws are engineered to meet the strict requirements of modern industrial and CNC equipment. Made from premium GCr15 bearing steel, these ball screws combine high hardness, excellent wear resistance, and stable mechanical properties to ensure smooth, low-friction linear motion over extended periods.

Key Features:

• • High-Precision Machining: Manufactured using both rolling and grinding processes, our ball screws offer tight tolerances and repeatable positioning accuracy, ideal for CNC machining centers, automation lines, and other precision applications.
• • Long Service Life: The robust GCr15 steel construction, combined with optimized internal circulation design, reduces wear and extends the operational lifespan of the screw assembly.
• • Internal Circulation Structure: Our ball screws feature an internal circulation design with recirculation caps that guide steel balls along a continuous, closed path. This compact structure ensures smooth ball movement, minimizes noise, and improves load distribution across the screw and nut.

• • Customization Available: We offer full customization services for ball screws, including non-standard dimensions, end machining, and preload adjustments to match your specific equipment requirements. Whether you need standard sizes or fully custom specifications, our team can provide tailored solutions to fit your project needs.
• How Ball Screws Improve Your System Performance
• Ball screws play a vital role in converting rotary motion into linear motion with high efficiency and precision. Unlike traditional lead screws, ball screws use recirculating steel balls to reduce friction, resulting in:
• • Higher efficiency and lower energy consumption
• • Improved system rigidity and load-bearing capacity
• • Reduced backlash and better positioning accuracy
• • Quieter operation and smoother movement
• These benefits make our SFU1605 ball screws ideal for applications where precision, reliability, and long-term performance are non-negotiable. From CNC routers and lathes to automated packaging machinery and industrial robots, our ball screws are built to perform under pressure.
