KTR-SI FRA

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.
