CNC builders and machinists, this double nut ball screw kit is a solid choice for your next project. It's a 16mm diameter screw with a 5mm lead (DFU1605/RM1605), and the total length is 750mm (about 29.53 inches). The kit includes the ball screw with standard end machining for BK/BF12 supports, a double ball nut (which reduces backlash for better accuracy), a pair of BK12/BF12 bearing blocks with locknuts and circlips, and a flexible coupler (usually 6.35mm bore – message if you need a different size). The precision grade is C7 (rolled thread), which is great for most CNC applications like routers, mills, or 3D printers. Double nut design means preload is built-in, so you get smoother movement and less play. These screws are made from GCr15 steel and are durable, with low friction and long service life. Installation is straightforward if you're familiar with linear motion systems. We can also customize the length or end machining if you provide drawings – just ask! Lead time is typically 7-10 business days. This is a complete kit that saves you from sourcing parts separately. Perfect for DIY CNC enthusiasts, small machine shops, or anyone upgrading their equipment. Get precise, reliable linear motion with this all-in-one ball screw package.
