In today’s automation environments, manufacturers are increasingly handling products that are lightweight, fragile, thin-walled, or irregularly shaped. Conventional mechanical grippers with rigid jaws often create challenges such as scratches, deformation, unstable gripping, or product damage.
The KOGANEI Rubber Hand Series offers a smarter solution.
Unlike traditional grippers, the Rubber Hand Series uses a one-piece inflatable rubber body that expands and contracts like a balloon. This unique design allows the gripper to gently wrap around the workpiece over a wide contact area, providing secure and stable handling without concentrated pressure points.
How It Works
The Rubber Hand operates using pneumatic pressure:
Air supplied into the rubber body causes it to inflate or contract
The rubber surface gently conforms to the workpiece shape
Wide-area contact improves stability and minimizes damage
Soft gripping enables handling of delicate materials safely
This innovative gripping method is ideal for automated systems that require both precision and gentle handling.
Grip Type RBG – Outer Diameter Gripping
The Grip Type RBG inflates inward, allowing the rubber body to softly wrap around the outer circumference of the workpiece.
