    The EGS04 low-profile precision rail is an “efficient guided system” that's suited for customers in lab automation and electronic assembly where applications require high speed and highly efficient point-to-point motion. Its stage base combines RGS-style screw supports and a ball-bearing profile rail for a lower carriage ride (<0.6 in. (16 mm)), higher speed capability, and more efficient, stiffer load support than competitor products.

     

    It provides a less complex and up to 50% smaller alternative to more traditional belt and gearbox designs and offers the advantage of an easily integrated bolt-in design to eliminate facets of a multi-component design.
