Fully Hiwin-Compatible, Drop-In Ready Engineered to match the specifications of Hiwin 3210 ball screws, our unit offers 100% interchangeability for easy retrofitting or new builds. No modifications needed—just install and go, with the same fit, function, and performance you expect from premium brands, at a fraction of the cost. 2. Versatile Precision Grades (C3/C5/C7) Tailored to meet diverse accuracy requirements: • C3 Grade: Ultra-precision performance with ±8µm/300mm cumulative lead error, perfect for high-end machining centers, semiconductor equipment, and metrology instruments. • C5 Grade: Balanced precision (±18µm/300mm) for general CNC machines, automation systems, and precision manufacturing lines. • C7 Grade: Cost-effective reliability (±50µm/300mm) for standard industrial machinery, packaging equipment, and general automation projects. 3. Durable Construction & Premium Materials Crafted from GCr15 bearing steel, a material renowned for its exceptional hardness, wear resistance, and fatigue strength, our ball screw ensures stable performance even under continuous heavy loads. The internal circulation design eliminates external return tubes, resulting in a compact, space-saving structure that reduces noise and vibration during high-speed operation. 4. Internal Circulation Design for Smooth, Efficient Motion The ball screw consists of the screw shaft, ball nut, steel balls, and internal return caps. Steel balls circulate within a closed path guided by built-in return caps, which: • Minimize impact noise and ball wear, enabling smoother, quieter operation • Reduce the overall nut diameter, making installation easier in compact equipment • Support high acceleration/deceleration rates without compromising precision • Boost transmission efficiency by reducing friction compared to traditional lead screws 5. Dual Manufacturing Processes for Every Need Choose between two production methods to match your application: • Rolled Screws: Economical, high-volume option ideal for standard automation and low-to-medium precision tasks • Ground Screws: Precision-finished for tight tolerances, smooth surface finishes, and superior performance in high-accuracy CNC and industrial applications 6. Extended Service Life & Low Maintenance Thanks to low-friction rolling contact and robust material selection, our ball screws offer: • Minimal backlash for consistent positioning accuracy over time • Reduced wear and tear, leading to fewer replacements and lower long-term costs • Compatibility with standard lubrication systems for easy upkeep Common Applications This Shuntai 3210 ball screw is widely used in: • CNC machining centers and lathes • Industrial automation equipment (pick-and-place systems, assembly lines) • Semiconductor manufacturing machinery • Medical equipment and precision measuring instruments • Packaging and material handling systems Fast, Reliable Delivery We understand the importance of minimizing downtime, which is why we offer 7-day lead times for standard orders, with shipping available from Shanghai ports to destinations worldwide.

Looking for high-performance ball screws to upgrade your CNC machining equipment or 3D printing machinery? Our precision rolled ball screws from Shuntai deliver reliable load-bearing performance, outstanding durability and flexible custom solutions, widely adopted across industrial automation, CNC lathe and desktop industrial 3D printing industries. Ball screws serve as the core transmission component of precision motion systems. Unlike traditional sliding screws, ball bearings roll between the screw shaft and nut during operation, which effectively distributes working load, boosts overall equipment rigidity and enhances the load capacity of your automation setup. Core Construction: Internal Circulation Ball Screw Structure Our mainstream internal circulation ball screw consists of four core parts: screw shaft, nut, steel balls and internal deflectors (return caps). 1.Steel balls run in a single closed loop inside the nut channel; 2.Built-in return caps span and link adjacent ball grooves inside the nut body; 3.Steel balls change movement direction via the inner return cap to form a fully enclosed circulating path. Since all return components are embedded inside the nut housing, this internal circulation design keeps the ball screw compact in outer dimension, saves installation space for your compact CNC and small-format 3D printer equipment, a key advantage for space-limited automated machinery designs. Key Product Specifications & Advantages Item Details Brand Shuntai Raw Material GCr15 bearing steel, carbon steel & bronze optional Production Process Rolled screw shaft / Ground screw shaft for different precision grades Core Feature Extra-long service lifespan, stable running with low friction Lead Time 7-day quick production & delivery Shipping Port Shanghai, China Two Craft Options to Match Your Needs 1.Rolled Ball Screw: Cost-effective option for standard precision CNC equipment, regular 3D printers and general automation machinery, balances performance and procurement cost; 2.Ground Ball Screw: Ultra-precision finished for high-end CNC machining centers and high-precision industrial 3D printing, meets strict micron-level positioning requirements. 3.We adopt premium GCr15 bearing steel as primary raw material, a common high-strength alloy for motion transmission parts. The material brings strong wear resistance and anti-fatigue property, directly extending the whole screw service life and cutting your long-term equipment maintenance and replacement expense. Bronze accessory alternatives are also available per your custom design request for special working environments.Custom Service for Global Buyers One of our biggest highlights is flexible customization.
