THK BNFN-V Series Full-Ball Type Precision Ball Screw (Double Nut, High Speed)
The THK BNFN-V Series uses a double nut preload method, combining two ball screw nuts with a spacer to eliminate backlash, and it’s built for high-speed operation on top of that. This makes it a solid choice where you need the accuracy of a double nut preload but also want to run at higher feed speeds than a standard double nut design allows.
It’s available in screw shaft diameters from 16mm to 50mm, giving you a good range of sizes for precision positioning applications.
