THK DKN Series Full-Ball Type Precision Ball Screw (Slim Nut, Double Nut Preload)
The THK DKN Series is a deflector-type precision ball screw with a compact, slim nut, using a double nut preload method where a spacer sits between two combined nuts to achieve a below-zero axial clearance and remove backlash.
It’s available in screw shaft diameters from 40mm to 63mm, giving you a slim, precise nut option where a double nut preload design is preferred over a single offset-preload nut.
