Product details

RotoClamp Inside

RotoClamp Inside - a compact clamping system for rotary applications.

In the standard version, RotoClamp Inside is fail-safe, as the shaft is fixed immediately and with great force in the event of a pneumatic failure.
Alternatively, we also offer you the active version with the reverse functional principle.
We have put together our standard sizes of RotoClamp Inside clamping elements for you here.

Tandem versions

For special requirements that require higher holding torques, the clamping systems can also be used in a tandem version. The holding torques increase by a factor of 1.8. Tandem versions must be ordered ex works; the clamping systems are adapted for this purpose.

Individual designs

Do you require a special design or custom-tailored contours? We would be happy to assist you with your project—please get in touch with us.

RotoClamp tandem versions

RotoClamp Inside Tandem

Our clamping systems are also available as a tandem version; the specified values increase by a factor of 1.8.

Please note:

These versions are already adjusted to the tandem function at the factory. A combination of clamping systems without prior processing is not possible.
