1. Why using the U-shape Guideway?
  The U-shape guideway, a u-shape structure which helps make the guideway and bottom pedestal together, has the advantages of compactness, high stiffness, high precision, and simple components. It is relatively lightweight and can create a highly precise positioning platform. In terms of space: although the size of assembly interface is similar to that produced by other manufacturers, the linear module made by HIWIN has a smaller U-shape guideway and contains less space. This design can make the major weight of U-shape guideway fall onto the bottom pedestal. High stiffness: With the best design using the finite element method, the stiffness of U-shape guideway can be improved. High precision positioning platform: accurately manufactured U-shaped guideway and ballscrew can reach the aim of high precision positioning through the stiffness of the guideway and the bearing.
