7 Function
Hydraulic pressure is applied to the housing. Under this pressure, the housing expands slightly and releases the shaft
connection, which is screwed to the rotation axis.
In the pressureless state, the housing resumes its original shape and clamps the shaft connection via the pretension
retained in the housing.
This pretension enables the holding torque absorption to be achieved in the clamped state.
The product is closed in a pressureless state and offers an integrated emergency function that ensures that all moving
components are held securely if the pressure drops or the entire system fails.
The product is not suitable for dynamic emergency braking.
