Product Overview
The FESTO FEN-25-160-KF guide unit is a precision guide device designed specifically for high torque load scenarios, belonging to the FEN series of the FESTO guide unit family. This product effectively prevents standard cylinders (such as DSNU and DNC series) from twisting during operation through circulating ball bearing guide technology, providing sub millimeter level positioning accuracy for scenarios such as workpiece handling, semiconductor manufacturing, and electronic assembly. Its core advantages are reflected in three dimensions: anti torsion performance, environmental adaptability, and modular design.
