🔧 CNC Ball Screws | Ball Screw Set | 2005 | SFU2005-4-410 (EM-BKBF17)
🔩 CNC Ball Screw Set – SFU2005-4-410 (EM-BKBF17)
📄 Product Description:
The SFU2005-4-410 Ball Screw Set is a precision-machined linear motion component designed for CNC machinery, 3D printers, automation systems, and industrial motion platforms. With a 20mm diameter, 5mm lead, and 410mm overall length, it offers an excellent balance of load capacity, accuracy, and smooth travel.
This set includes a preloaded SFU2005 ball nut for reduced backlash and precision positioning. The screw is pre-machined to EM-BKBF17 standard, making it plug-and-play with BK17 (fixed) and BF17 (floating) end support units.
