RotoClamp Outside | HEMA Group

RotoClamp Outside is a compact clamping system for rotary applications. In the standard version, RotoClamp Outside is fail-safe, as the shaft is immediately fixed with great force in the event of a pneumatic failure. Alternatively, we also offer the active version with the opposite functional principle.

Below we have put together an overview of the RotoClamp Outside clamping elements in standard sizes for you.

Tandem version

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

Do you need a special version, individually tailored contours?
We would be happy to support you with your project - ask us.

RotoClamp tandem version - shown using the Inside version

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.
