Coupling description

The POLY-NORM® coupling is a torsionally flexible, shear type shaft coupling. It has an axial plug-in design with a unique short over all length. The POLY-NORM® can be used in nearly all types of machinery and is ideal for the pump industry.

The POLY-NORM® coupling compensates for shaft misalignment of all kinds and safely transmits the torque.
