KTR-SI FRA with POLY-NORM®

5 - 3,000 Nm / Idle rotation and automatically re-engaging overload coupling

Downloads

The overload coupling KTR-SI FRA with POLY-NORM is an idle rotation safety coupling combined with the torsionally flexible POLY-NORM shaft coupling.

The special overload coupling provides all properties and options of a safety coupling in combination with the compact and torsionally flexible POLY-NORM.

Features

max. operating temperature 80 °C
damping vibrations
electrically insulating
axial plug-in
compensating for displacements (axial, radial, angular)

Product Details

Specifications for: KTR-SI FRA with POLY-NORM®

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 of the drive 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.
