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
offers high rigidity against bending moment. This structural feature
allows for integrated framework of machinery or equipment and can
be cantilevered. Additionally, the slide block contains 4 ball circuits
which delivers high load capacity, high accuracy and high rigidity.
