POLY-NORM® torsionally flexible, fail-safe shaft couplings
POLY-NORM® AR

POLY-NORM® AR

0 - 67,000 Nm / torsionally flexible, fail-safe shaft coupling

Configurator

The torsionally flexible, fail-safe shaft coupling POLY-NORM AR is a compact two-part shaft coupling for torsional vibration-damping power transmission.

The hubs made of cast iron identical in design make the standard version POLY-NORM AR specifically low-priced.For mounting the shaft coupling the hubs are simply pushed onto the shafts and fastened axially by means of setscrews.

Features

two-part shaft coupling (pump coupling) for torsional vibration-damping power transmission
low-cost standard type
axial plug-in, easy assembly
maintenance-free
compact: small shaft distance dimension

Product Details

Specifications for: POLY-NORM® AR

With the coupling configurator for torsionally flexible, fail-safe shaft couplings POLY-NORM you can design the suitable coupling based on given technical data.

Go to configurator

The POLY-NORM® shaft couplings are characterized by their compact design. The torque is transmitted via elastomers between the cams that furthermore serve for compensating for displacements and damping shocks and torsional vibrations.

Applications of our torsionally flexible, fail-safe shaft couplings:

The POLY-NORM shaft couplings are used in almost every range of mechanical engineering, mainly in the pump industry (pump coupling).

Component variance of fail-safe shaft coupling:

High adaptability with low variance by an optimally graded construction kit system: The elements of the POLY-NORM® shaft coupling within one size can easily be combined with each other. This allows to realize various shaft distances with the same basic component.

Function of fail-safe shaft coupling: The POLY-NORM shaft coupling consists of two hubs the cams of which are each put in the tailor-made clearance of the other hub by half.

This compact design of the shaft coupling allows to connect the shafts with a particularly short shaft distance dimension. The elastomer arranged between the cams transmits torques while compensating for any kind of displacement.
