THK BNT Series Full-Ball Type Precision Ball Screw (Square Nut)
The THK BNT Series is a precision ball screw with a square nut and a return-pipe ball circulation system, built with a precision-ground screw shaft for smooth, accurate motion. It doesn’t require a preload, which keeps design and assembly straightforward.
It’s available in screw shaft diameters from 14mm to 45mm, giving you a solid range of sizes to fit different feed mechanism designs where a square nut mounting style is preferred.
