When standard ball screws just won’t fit your unique machinery requirements, our custom non-standard ball screws deliver the tailored precision, durability, and performance you need. As a professional OEM manufacturer specializing in ball screw solutions, we design and produce custom models like the 4005 non-standard ball screw nut assembly, engineered to meet the exact specifications of CNC machines, automation systems, and industrial equipment worldwide. Why Choose Our Custom Non-Standard Ball Screws? Our non-standard ball screws are built from the ground up to solve your toughest linear motion challenges. Here’s what sets them apart: ✅ Fully Customizable to Your Exact Needs No two industrial applications are the same, so we offer complete customization of dimensions, materials, and end machining. Whether you need a specific diameter, lead, length, or nut configuration, our engineering team works with you to design a ball screw that fits your equipment perfectly. We handle both rolling and ground screw manufacturing to meet different accuracy and performance requirements. ✅ Premium Materials for Unmatched Durability We craft our ball screws from high-quality materials, including GCr15 bearing steel, stainless steel, alloy steel, carbon steel, brass, and aluminum. The use of GCr15 bearing steel ensures exceptional hardness, wear resistance, and long service life, even in high-load, continuous-operation environments. ✅ Precision Manufacturing for Reliable Performance Every ball screw undergoes rigorous production processes, including cold rolling, CNC grinding, precision turning, and straightening. Our accuracy grades (C3, C5, C7) guarantee consistent positioning, repeatability, and smooth operation—critical for applications like CNC machining, robotics, and automation. The recirculating ball bearing design minimizes friction, ensuring efficient, quiet linear motion conversion from rotational input. ✅ Built for Long-Term Industrial Use Our custom ball screws are engineered with key performance features: High reliability for continuous industrial use Exceptional durability to reduce maintenance and replacement costs High rigidity and preload stability under heavy loads Smooth, low-friction operation for consistent performance Long service life, backed by strict quality control✅ OEM-Ready Solutions with Flexible TermsAs an OEM factory, we offer streamlined production, assembly, and quality control processes, ensuring every ball screw meets your specifications. We support small-batch testing orders (minimum 1 piece for samples) and provide custom packaging to meet your shipping and handling requirements. With fast lead times and shipping from Shanghai port, we get your custom ball screws to you quickly and safely.Applications of Custom Non-Standard Ball Screws Our custom ball screws are ideal for a wide range of industrial applications, including: CNC machine tools and machining centers Industrial automation and robotics Medical equipment and laboratory machinery Aerospace and defense systems Packaging and printing machinery Any equipment requiring specialized linear motion solutionsReady to Design Your Custom Ball Screw?Don’t settle for off-the-shelf solutions that don’t fit your needs.

Looking for a compact, high-efficiency ball screw for precision industrial equipment and lab instruments? Our custom 8mm diameter miniature ball screw from Shuntai delivers reliable rotary-to-linear motion conversion, fully customizable in shaft length and end machining to match your unique equipment drawings. Mini ball screws are the core component that seamlessly converts rotational motion into precise linear movement, and vice versa. Composed of a screw shaft, ball nut and circulating steel balls, this mini ball screw redefines traditional sliding transmission by adopting rolling friction design. The drastically reduced friction resistance enables smoother, quieter and more energy-efficient operation, making it a staple for all types of precision machinery and analytical instruments worldwide. Core Product Specifications Item Details Product Name Miniature Ball Screw Model Customized Per Customer Drawings Brand Shuntai Raw Material GCr15 Bearing Steel Production Technology Rolled Screw Shaft / Ground Screw Shaft Key Advantage Extended Service Life Lead Time 7 Days Fast Production Shipping Port Shanghai, China Why Choose Our 8mm Mini Ball Screw? 1.Premium GCr15 Bearing Steel Construction We adopt high-grade GCr15 bearing steel as raw material. After precise heat treatment, the shaft and nut gain outstanding hardness, wear resistance and anti-fatigue performance, laying the foundation for long-term stable operation. 2.Two Processing Options for Different Precision Needs • Rolled ball screw: Cost-effective, fast delivery, ideal for general automation equipment • Ground ball screw: Ultra-high positioning accuracy, low backlash, perfect for high-precision testing instruments and medical devices 1.Full Customization Support No standard fixed sizes limit your design. We can machine the screw end to your required shape, thread, mounting shoulder, and adjust the total shaft length strictly following your technical drawings. The 8mm shaft diameter hits the sweet spot between compact size and load capacity for miniature automation modules. 2.Long Service Life & Low Maintenance Thanks to rolling friction transmission, friction loss is far lower than trapezoidal lead screws. Less wear on internal balls and raceways cuts down maintenance frequency and replacement costs for your production line. 3.Fast Lead Time & Convenient Global Shipping Standard custom orders finish production within just 7 working days. We ship all goods from Shanghai Port, with mature logistics cooperation to support sea, air and express delivery to all global regions. Wide Application Scenarios This 8mm miniature ball screw fits countless precision linear motion projects: • Laboratory analytical & testing instruments • Small automated assembly machinery • Medical micro motion equipment • 3D printing devices • Optical inspection & camera positioning modules • Mini CNC micro-machining equipment About Shuntai Manufacturer Shuntai is a professional ball screw manufacturer focusing on custom linear motion transmission parts.
