THK DKN Series Full-Ball Type Precision Ball Screw

The DKN Full-Ball Type Precision Ball Screw is a deflector-type ball screw featuring a slim nut design.

A double-nut preload structure is used, where a spacer is inserted between two combined ball screw nuts to achieve a below-zero axial clearance under preload. This design enables smooth, stable motion while maintaining a compact nut profile, making it suitable for high-precision applications with limited installation space.
