If you’re sourcing reliable, high-precision linear transmission components for CNC machines, automation equipment, 3D printers, or robotic systems, the SFU1605 ball screw assembly is one of the most versatile, cost-effective options on the global market. As a professional OEM ball screw manufacturer based in China, Shuntai provides complete SFU1605 ball screw kits with flange nuts and BK12/BF12 support units, fully customized to match your machinery’s exact performance demands.Ball screws serve as the core mechanical part that converts rotary motion into smooth linear movement. Unlike traditional lead screws, they utilize circulating steel balls rolling between the screw shaft and nut raceway, delivering lower friction, higher efficiency, longer service life, and consistent positioning accuracy—critical advantages for all precision industrial machinery. Core Specs of Our SFU1605 Ball Screw AssemblyOur standard 1605 ball screw features a 16mm shaft diameter with a 5mm lead, pre-finished shaft ends compatible with BK12/BF12 bearing supports, paired with a flange ball nut for easy mounting. Below are the full product parameters for reference: Item Detailed Specifications Model SFU1605 Main Material GCr15 bearing steel (standard); stainless steel, alloy steel, carbon steel optional Manufacturing Process Rolled thread screw shaft; CNC grinding & finishing for high precision Precision Grade C3 / C5 / C7 for different accuracy demands Usable Length Range 10mm to 6000mm, custom cut to your required size Standard Shaft Diameter Range 5mm – 65mm (full series ball screws available) Standard Lead Options 3mm – 300mm Supporting Accessories Flange ball nut, BK/BF fixed/floating support units MOQ 1 unit for sample testing, bulk orders supported Lead Time 7 working days for standard stock models Shipment Port Shanghai Port for global sea & air freight Key Advantages of Shuntai Ball Screws As a direct OEM factory with complete production lines, we control every production step from raw material processing to finished product inspection, bringing 5 core benefits to overseas buyers: High Precision & Stable Operation Our rolled and ground ball screws maintain tight tolerance standards. Circulating ball design eliminates sliding friction, ensuring ultra-smooth linear movement with minimal vibration during high-speed operation. Extended Service Lifespan & High Durability GCr15 bearing steel undergoes strict heat treatment for strong wear resistance, hardness, and anti-fatigue performance. Proper preload design reduces backlash, preventing rapid wear even under continuous heavy-load operation. Strong Rigidity & Adjustable Preload Custom preload options eliminate internal clearance, boosting overall structural rigidity. Ideal for high-speed, high-load automation equipment that requires zero-backlash positioning. Full Customization Capacity We support OEM customization across materials, shaft length, thread lead, end machining styles, nut types, and surface treatments. Our workshop is equipped with cold rolling machines, CNC grinders, lathes, straightening machines, and drilling equipment to process fully tailored ball screw assemblies. Reliable Factory Quality Control Every ball screw goes through a 100% quality inspection workflow before shipment. We maintain sufficient raw material and finished product inventory to guarantee fast, safe delivery for small sample orders and mass industrial purchases alike.Wide Industry Applications for SFU1605 Ball Screw The compact SFU1605 size makes it a universal linear motion component for countless devices: CNC milling, lathe, and engraving machines Automated assembly production lines 3D printing equipment Medical precision automation devices Robotics and linear motion actuators Packaging and labeling machinery Measuring and inspection precision instrumentsWhy Choose Shuntai as Your Ball Screw Supplier?
