Festo KP-25-5000
Clamping Cartridge

Festo is a German automation company that produces and sells pneumatic and electrical control systems and drive technology for factories and process automation.

The clamping cartridges/units use spring force to hold round material in any required position. They can stop and hold material for long periods, even in applications with varying loads, fluctuating oper-ating pressure and system leaks. The clamping force is released by pressurising the clamping cartridge. The clamping cartridges/units can be mounted in any position. Clamping cartridges/units are not suitable for positioning. The clamping cartridge KP and the clamping units KPE, KEC, KEC-S are standalone components.
