High-Precision Custom Ball Screws for CNC Machine Tools: Reliable, Durable, and Cost-Effective Solutions
May 07, 2026
If you’re sourcing high-performance linear motion components for CNC machines, automation systems, or industrial equipment, you know how critical ball screws are to your operations. A single faulty or low-quality screw can lead to costly downtime, precision errors, and production delays. At Shuntai, we specialize in manufacturing custom ball screws that solve these challenges—delivering exceptional accuracy, long service life, and consistent performance tailored to your unique requirements.

Why Choose Our Custom Ball Screws?
Ball screws convert rotational motion into linear motion, and they’re the backbone of precision machinery. But not all ball screws are created equal. Here’s how our products stand out:
🔧 Precision That Never Compromises
We offer ball screws in accuracy grades C3, C5, and C7, with standard diameters from 5mm to 65mm and leads from 3mm to 300mm. Whether you need ultra-tight tolerances for high-speed CNC machining or reliable positioning for general automation, our screws deliver the repeatability and precision you demand. Lengths can be customized from 10mm up to 6000mm, so we can match your exact design specifications.
🛡️ Built to Last, Engineered for Toughness
Our ball screws are crafted from premium materials including GCr15 bearing steel, carbon steel, alloy steel, stainless steel, brass, and aluminum—ensuring durability in even the harshest industrial environments. The rolling screw manufacturing process, combined with CNC grinding, precision machining, and straightening, eliminates defects and maximizes wear resistance. The result? A ball screw that maintains its performance over years of heavy use, reducing maintenance costs and unplanned downtime.
⚙️ High Rigidity, Smooth Operation
Designed with optimized preload and rigidity, our ball screws eliminate backlash and deliver stable, vibration-free movement. This is critical for applications like high-speed machining, where even minor vibrations can ruin part quality. The smooth ball circulation in our external loop design ensures quiet, efficient operation, even under heavy loads.
🎯 Fully Customizable to Your Needs

Every industrial application has unique requirements—and we don’t believe in one-size-fits-all solutions. We tailor our ball screws to your exact specifications:
- • Custom materials for corrosion resistance or weight reduction
-
- • Specialized end machining to fit your assembly
-
- • Precision grades matched to your performance needs
-
- • Packaging designed for safe shipp
