The Single Roller Principle
The torque is transmitted via rollers which are pressed by Belleville springs into detents.When the preset limit torque has been reached, the detent ring is displaced but is prevented by its particular design from disengaging completely. There is therefore no disengaging of input and output.
Advantages
- Output is fully driven even in case of overload
- Integral fixed bearing
- Driving keyway in the 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, a limit sensor indicates the overload.
- There is no interruption of torque transmission between drive and output.

Notes
Torque setting
The limit torque can be set at the factory on request. 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
