GnB Motion System KGB Series Ball Screw Actuator (Open Type)

GnB Motion System KGB Series Ball Screw Actuator (Open Type)

The KGB Open Type is a ball screw driven single-axis actuator with an integrated guide-slider structure instead of separate LM blocks.

Key features

  • The guide-slider design lowers the actuator height by roughly 30-40% compared with conventional LM-guide actuators while widening the slider span for higher moment capacity
  • An aluminum base keeps the unit lightweight, and the ball screw unit is assembled directly into the slider for rigidity and repeatability
  • Grease nipples on both sides of the slider allow lubrication from either direction after installation
  • Body widths range from 30 mm to 160 mm with rolled or ground ball screws, in-line or folded motor layouts and strokes up to 1400 mm
