Clamping cylinders hold or clamp a workpiece either directly using a pneumatically operated clamping element or using kinematics. The clamping element is swivelled out of the working area when it is inactive. They can realise very high holding forces with low energy input thanks to kinematics. At Festo, we differentiate between clamping modules, linear/swivel clamps and hinge cylinders.
Clamping modules are extremely flat diaphragm actuators with short strokes that can be used for a wide range of clamping tasks. Thanks to their flat design, the clamping modules can be used in many situations where other clamping cylinders reach their limits, such as in narrow spaces. And a clamping force of up to 1640 N can be achieved. There are round and elongated designs with which both flat as well as more linear clamping tasks can be implemented. The hermetically sealed design of the clamping modules also makes them suitable for harsh, dusty ambient conditions.
In our current range you will find clamping module EV – a short rodless cylinder with diaphragm. The EV is single-acting, has a reset function and is hermetically sealed.
