Clamping Element LE2 Series

In accordance with the theory of booster, low air pressure is converted to high oil pressure, and the force is taken outside by hydraulic piston to use as power. With booster and clamp head in one unit, it is small and lightweight for easy application.
  • With the cylindrical shape, both length and exterior dimension are small and it is also very compact.
  • As cylinder volume is extremely small, the air consumption can be minimized.
  • The mounting position can be adjusted with clamp ring, and the clamping will be performed quickly and completely with short stroke.
