THK BNT Square Nut Full-Ball Precision Ball Screw

The THK BNT Full-Ball Precision Ball Screw is designed for compact and accurate positioning. Mounting holes are machined directly into the square nut, so it can be mounted to the machine without a separate housing. This helps save installation space.

The BNT uses a return-pipe design and has no preload. Its square nut allows direct mounting and helps simplify the machine structure. The design is suited to applications that require precise linear motion in a compact layout.

The THK BNT Full-Ball Precision Ball Screw is available with screw shaft diameters from 14 to 45 mm. The series has a DN value of 70,000 and is available in several size and lead combinations.
