Overload systems KTR-SI FRA by KTR Systems GmbH

KTR-SI FRA idle rotation and automatically re-engaging overload couplings

In case of overload the KTR-SI FRA overload couplings uncouple driving and driven side while protecting the drive train from damages.

After eliminating the overload the KTR-SI FRA can automatically be re-engaged by reversing the direction of rotation for a short time. As a result this version is optimally suitable for positions difficult to access. 

The KTR-SI FRA idle rotation and automatically re-engaging overload couplings are available as a flange type FT or in combination with the POLY-Norm flexible coupling (shaft-to-shaft connection). The low-backlash, positive-locking ball engagement system allows for optimum overload protection for torques up to 3,000 Nm.

Applications of our idle rotation overload coupling KTR-SI FRA (safety coupling):

Typical applications of these overload couplings are, for example, crushers, agricultural machinery, conveyor systems, packaging machines, textile machines, marine applications, steel mills, extruders.

Overview of our overload couplings KTR-SI FRA:

Advantages
  • Idle rotation safety coupling (load separating)
  • Automatic re-engagement when reversing the direction of rotation
  • High repeatability
  • Flange type to connect toothed belt pulleys or sprockets
