Internal hole grippers

Our pneumatic internal hole grippers with standard diameters of 20 to 99 millimeters are designed for safe, automatic gripping and handling of sensitive parts, such as grains of sand in foundries.

Our hole grippers are made of chemically resistant polyamide. This makes them approximately 60% lighter than conventional, internal hole grippers made of rubber, ensuring them a longer service life. 

The SCHUNK polyamid modules have proven to be extraordinarily robust and friction-resistant. The gripper is comparable to a clamping pin, has a one-part structure as well as a closed membrane system, which is thus fully resistant to dirt.
