Overload systems KTR-SI by KTR Systems GmbH

KTR-SI overload couplings

The KTR-SI overload couplings are torque limiters available in various types of engagement (DK or SR, automatically engaging and FR load-separating, idle rotation) and designs (overload coupling with flange types or in combination with ROTEX jaw couplings).

Due to the wide variety of the overload couling the low-backlash and positive-locking ball engagement system provides solutions for almost every appplication.


Overview of our KTR-SI overload coupling:

  • for torques up to 8,200 Nm
  • Ratchet and synchronous as well as fail-safe and idle rotation type
  • High repeating accuracy
  • Low-backlash torque transmission
  • Optional disengagemet with overload by limit switch mode
  • Maintenance-free Easy assembly and torque setting
