Delta's Ball Screw Driven Linear Stage LU Series has its motor and screw in a patented non-coupling installation design. It features high stiffness, low inertia ratio, and fast response. The rated thrust is 181 to 905N, and the repeatability and setting time is better than one with coupling. It is also in a compact design, which saves space and is suitable for replacing traditional screw applications for higher stability and smaller space usage.
