Custom Ball Screw

In precision manufacturing and automation, the efficiency, rigidity, and service life of your motion control components directly determine the performance of your entire system. When looking for a high-quality replacement for TBI ball screws that matches or exceeds industry standards, SHUNTAI’s ball screws stand out as a cost-effective, high-performance solution. Designed for seamless compatibility and built to last, these ball screws deliver the precision and reliability your applications demand. Why Choose SHUNTAI Ball Screws? SHUNTAI ball screws are engineered to replace all TBI ball screw series, offering identical performance with enhanced durability and competitive lead times. Crafted from premium GCr15 bearing steel, a material renowned for its high hardness, wear resistance, and fatigue strength, these ball screws are built to withstand the rigors of continuous, high-load operation. Our ball screws are manufactured using two advanced processes: rolled screws for cost-effective, high-volume applications and ground screws for ultra-precision requirements. This dual manufacturing capability allows us to cater to a wide range of industries, from standard automation to aerospace-grade precision applications. Key benefits include: • Enhanced System Rigidity: By distributing loads through rolling contact, our ball screws reduce friction and improve the overall rigidity of your equipment, leading to smoother operation and better performance. • Long Service Life: The combination of high-quality materials and precision manufacturing ensures these ball screws deliver extended service life, reducing maintenance needs and downtime. • Quick Delivery: With our Shanghai-based shipping port, we offer a fast 7-day delivery turnaround, so you can get the components you need without long lead times. Versatile Applications Across Industries Ball screws are the backbone of precision linear motion, used in applications that demand accuracy, speed, and reliability. SHUNTAI ball screws excel in these key sectors: 1. CNC Machine Tools   From milling machines to lathes and drilling equipment, our ball screws enable fast, precise positioning, boosting both machining efficiency and part accuracy. They ensure smooth, repeatable motion for even the most complex cutting operations. 2. Industrial Machinery   Injection molding machines, presses, and textile equipment rely on ball screws to transmit high torque and heavy loads consistently. SHUNTAI ball screws provide the robust performance needed to keep these industrial workhorses running reliably. 3. Robotics & Automation   Precision is critical in robotic arms and automated systems. Our ball screws deliver the exact motion control required for joint positioning and linear movement, ensuring robots operate with accuracy and stability. 4. Aerospace & Defense   For aircraft landing gear, engine components, and satellite platforms, SHUNTAI ball screws offer the high precision and dependability needed to meet strict aerospace industry standards. 5. Medical Equipment   From surgical robots to CT scanners and MRI machines, our ball screws provide the smooth, stable motion control essential for medical device accuracy and patient safety. Ready to Upgrade Your Motion Control System?   Whether you’re looking to replace existing TBI ball screws or source new components for your project, SHUNTAI ball screws offer a reliable, high-performance alternative that meets your technical requirements and budget. With a focus on quality, compatibility, and fast delivery, we make it easy to keep your operations running smoothly.  

If you’re building 3D printers, small CNC equipment, lab testing machinery, or light-duty automated assembly lines, you’ve likely searched for reliable, affordable linear drive components. Today we’re breaking down our stainless steel trapezoidal lead screws (T5/T6/T8/T10/T12 series) — a top alternative to custom ball screws for low-to-medium load linear movement, manufactured right here in China with strict OEM quality standards. What Makes Our Trapezoidal Lead Screws Stand Out? Our full range T5, T6, T8, T10, T12 trapezoidal lead screws are engineered with stainless steel screw shafts paired with wear-resistant brass nuts, designed for smooth, consistent linear translation. Unlike generic low-grade lead screws on the market, every unit goes through our complete precision machining workflow, mirroring the strict production standards we apply to our custom ball screw lineup. Premium Raw Material Selection • We offer multiple material options to match different working environments: • Stainless steel: Anti-rust, ideal for humid, laboratory or food-adjacent equipment • Alloy steel & carbon steel: High strength for heavier load industrial machinery • Brass & aluminum accessories: Self-lubricating, low noise friction pairing Full Precision Manufacturing Process Every screw undergoes rigorous shaping and finishing via: cold rolling, CNC grinding, turn-milling, precision CNC machining, lathe processing, milling, drilling and straightening machines. This multi-step production eliminates shaft bending, uneven thread pitch and surface burrs — common flaws from simple one-step manufacturing. Consistent Accuracy Grades Our lead screw production follows the same precision control system as our custom ball screws, supporting accuracy classes C3, C5, C7 to meet your tolerance requirements, whether you need ultra-tight positioning for lab instruments or standard precision for hobby automation machines. Key Performance Advantages of Our Lead Screw Assemblies Long Service Life & High Durability The matched stainless steel thread and brass nut combination creates natural self-lubricating friction, reducing wear without frequent oil maintenance. Perfect for long-running unattended equipment like 3D printers. Stable, Vibration-Free Operation Carefully calibrated thread pitch and perfectly straightened screw shafts ensure quiet, smooth movement at low to medium speeds, no jitter or stalling during continuous reciprocating motion. Strong Structural Rigidity & Stable Preload Custom brass nuts (flange type, square mounting block type as shown in our product photo) deliver adjustable preload, eliminating backlash for precise repeat positioning. High Operational Reliability 100% in-house quality inspection throughout every production stage. Every finished screw is tested for straightness, thread consistency and nut fit before packing. Flexible OEM & Custom Service for Global Buyers As a professional OEM linear motion component factory, we tailor every detail to your project specs: Low minimum order quantity: 1 unit available for prototype sample testing Full customization: Custom shaft length, thread pitch, end machining, nut mounting style Custom packaging: Protective anti-rust wrapping and export-grade cartons per your shipping requirements Large in-stock inventory for standard T5-T12 models, fast global shipping with secure packaging to avoid transit damage We don’t only supply standard trapezoidal lead screws — we also produce non-standard custom ball screws with identical strict quality control, supporting small prototype orders and mass industrial bulk orders for distributors, machinery manufacturers and equipment builders worldwide. Common Applications for T5-T12 Trapezoidal Lead Screws Many overseas buyers rely on middlemen for lead screws, paying marked-up prices and facing unpredictable lead times.
