Backlash-free overload systems KTR-SI Compact by KTR Systems GmbH

Backlash-free safety couplings

Safety coupling in ratchet and synchronous type

The design of our safety couplings is based on backlash-free, positive-locking ball engagement principles allowing for high repeatability and shaft reaction times through the entire service life. 

Operation of safety couplings:

In case of overload the ratchet components (balls) of the safety coupling leave their indentations generating a relative movement between driving and driven side. In this way the safety couplings prevent damage caused by overload reliably. 

An optional limit switch provides a signal for control operations or can be used for switching off the drive.


Damage due to overload is reliably prevented

  • Ratchet and synchronous type
  • High repeatability
  • Backlash-free torque transmission
  • Optional switching off with overload by limit switch mode
  • Maintenance-free
  • Easy assembly and torque setting
