NB's BG type is a compact single axis actuator which integrates a slide guide and precision ball screw. BG type offers compact dimensions and outperforms conventional positioning tables. This is made possible by a unique "U" shaped guide rail and slide block which provides multiple functions of a guide block and a ball screw nut combined into a single unit. The "U" shaped guide rail design offers a high rigid structure resistant to bending. This structural feature allows for integrated framework of machinery or equipment and may be one-end supported. Additionally, the slide block contains 4 ball circuits which delivers high load capacity, high accuracy and high rigidity.
