Clamping cylinders hold or clamp workpieces either directly with a pneumatically operated clamping element or via kinematics. The clamping element is swiveled out of the working area in the inactive status. Very high holding forces can be achieved with low energy consumption using kinematics. At Festo, we distinguish between clamping modules, linear/swivel clamps and hinge cylinders.
Clamping modules are extremely flat diaphragm actuators with short strokes for a wide range of clamping tasks. Where other clamping cylinders reach their limits, clamping modules offer a wide range of possibilities. For example, due to their flat design, they can be used in narrow gaps. A clamping force of up to 1640 N is possible here. There are round and elongated designs that can be used to achieve both flat and more line-oriented clamping tasks. Clamping modules are also suitable for use in harsh, dusty ambient conditions due to their hermetically sealed design.
In our current range you will find the EV clamping module - a short rodless cylinder with diaphragm. EV is single-acting, has a reset function and is hermetically sealed.
