How to order

QGB 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 base unit. Up to 6 reed switches can be mounted. This model does not support stroke check with Proximity switches.

  • The material of internal seals of grippers is nitrile rubber. If the fluororubber seals are needed, please consult Kitagawa distributor.
