RotoClamp Inside | HEMA Group

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 need a special design, individually coordinated contours?
We would be happy to support you with your project!

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.
