The Single Roller Principle
The torque is transmitted via rollers which are pressed into detents by Belleville springs. When the preset limit torque has been reached, the detent ring moves axially and the SIKUMAT disengages. A locking mechanism holds the detent ring while it is in disengaged mode.
Advantages
- Disengages in case of overload - separation of input and output o Integral fixed bearing
- Keyway in connecting flange for maximum torque capacity
- Calibrated micro adjustment of torque setting possible, even postinstallation
- Exchange of current torque limiters possible
- Cost effective
Function
- When the preset limit torque has been reached the SIKUMAT disengages the input and output.
- After the overload has been eliminated the SIKUMAT can be switched on again manually.
- This means that an axial switching force must be applied to the switching ring.

Notes
Torque setting
If requested, the limit torque can be set at the factory.Setting or modification of the limit torque can also be carried out by the customer. See operating instructions for further details.
Proximity switch
The overload can be indicated by a non-contact or a mechanical proximity switch.
Speed Control ESC
The RINGSPANN speed control ESC (Electronic Speed Control) monitors speed deviations and speed differences safely and also under difficult operating conditions.see ESC
