POLY-NORM AR 55 HUB 3N 21MM

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. Applications of our torsionally flexible, fail-safe shaft coupling:The POLY-NORM AR shaft coupling is used in almost all fields of general engineering, here mainly in the pump industry (pump coupling).
