  • Ideal for machining environments with cutting chips, dust, coolant fluid, etc. (IP67)
  • Large ID gripping force
  • Unique sealing structure reduces the number of pipes

How to order

NPG3 series
  • Please install a check valve in the air-pressure circuit so that the gripper will not release a workpiece even if the air pressure drops down.

  • When the jaw stroke is detected by the reed switches, mount reed switched on the grooves on the outer periphery of the product. Up to 2 reed switches can be mounted.
