NSK offers a new line of miniature linear guides for applications in many industries especially the medical industry which not only requires small sizes, but also quiet and clean operation. Interchangeable rails and sliders allow for more cost-effective replacements and faster delivery. Maintenance-free operation with K1™ Lubrication Units offers reduced risk of mechanical failure with longer operating life, while the unique structure of the ball slide is designed to prevent dust generation.  Both a miniature version, the PU Series, and a miniature-wide version, the PE Series, are available.
