Introduction： In the world of CNC machining, industrial automation, and precision motion control, the reliability and accuracy of every component directly determine the performance of the entire system. At Shuntai Precision, we specialize in manufacturing high-quality, custom-engineered ball screws, and our 40mm SFU1605 CNC ball screw stands as a benchmark for durability, precision, and versatility. Whether you’re upgrading a CNC router, automating a production line, or building a custom industrial machine, this ball screw delivers the smooth, efficient linear motion your operations demand. What is an SFU1605 Ball Screw? The SFU1605 is a standard, widely used ball screw model in the global industrial market, defined by its core specifications: 16: Screw shaft diameter of 16mm 05: Lead (distance the nut travels per full rotation) of 5mm 40mm: Customizable shaft length (we offer tailored lengths to fit your exact application requirements) Unlike traditional lead screws, ball screws use recirculating steel balls between the screw shaft and nut to convert rotational motion into linear motion with minimal friction. This design delivers 90%+ efficiency (compared to just 20-30% for lead screws), reducing energy consumption, heat generation, and wear for long-term, high-precision operation. Our SFU1605 ball screw features an internal circulation structure, a compact and reliable design where the return guide is installed inside the nut. This structure allows steel balls to circulate in a closed loop within the nut, creating a streamlined, space-saving assembly ideal for CNC machines, 3D printers, and automated equipment with limited installation space. Key Features & Advantages of Shuntai’s SFU1605 Ball Screw The SFU1605 ball screw is a versatile component used across a wide range of industrial and commercial applications, including: 1. Premium Material for Long Service Life We manufacture our SFU1605 ball screws using GCr15 bearing steel, a high-carbon chromium alloy renowned for its exceptional hardness, wear resistance, and fatigue strength. This material ensures the screw shaft and nut can withstand heavy loads, high speeds, and continuous operation, delivering a significantly longer service life than standard steel alternatives. 2. Dual Manufacturing Processes for Versatility We offer two production processes to match your application needs: · Rolled Screw: Cost-effective solution for general industrial applications, with excellent surface finish and dimensional accuracy. · Ground Screw: High-precision option for demanding CNC machining and automation systems, delivering micron-level accuracy and ultra-smooth motion. 3. High Load Capacity & System Rigidity Ball screws distribute load across multiple steel balls during operation, drastically improving the rigidity and load-bearing capacity of your motion system. Our SFU1605 model is engineered to handle axial loads up to industry standards, making it suitable for heavy-duty CNC milling, lathe operations, and automated assembly lines. 4. Fully Customizable to Your Requirements We understand that every industrial application has unique specifications. Our SFU1605 ball screw supports full customization, including: · Custom shaft lengths (from standard 40mm to extended lengths for large-scale machines) · Custom nut flanges, end machining, and mounting options · Matching support bearings, couplers, and accessories for complete system integration · Custom lead and accuracy grades to meet your precision requirements 5. Secure Packaging & Fast Global Shipping All our ball screws are packaged in sturdy wooden cases to protect against damage during international shipping. We ship from Shanghai Port, with a standard 7-day lead time for production and fast delivery to Malaysia, Southeast Asia, and global markets, ensuring your components arrive ready for installation.
