Pneumatic Shaft-Locking Clamps are designed for quick change applications. In the pneumatic version, when connected to air, the clamp allows clamping/unclamping in one operation. They are perfect for secure clamping of sliding shafts and for use on machines where many clamping or unclamping cycles are run, or for multi-clamping applications. With air supply, remote operation is also possible at places out of reach, or hidden places like the backside of machines, and for maintenance or machine appearance.
