In coiled spring expansion clamping systems with rotational application of force, the coiled springs are enlarged by rotation in addition to compression. This allows greater distensions, even in full steel designs!

Coiled spring expansion clamping systems were developed and protected. These systems can be delivered by us as customised designs. We would be glad to receive your requests! The rights cannot be sold or licensed!
Pneumatic coiled spring expansion clamping gripper used for gripping in bore holes. Especially suited for gripping in high temperatures! Such grippers are able to produce great forces and can achieve differences in diameter of about 7 mm at a diameter of e.g. 60 mm.
