The POLY-NORM® coupling is a torsionally flexible, shear-type shaft coupling, which stands out in particular on account of its short design. It can be used in almost all sectors of mechanical engineering and the pump industry. It is assembled by axially plugging the hubs into each other and impresses with its ease of assembly and maintenance-free design.
This coupling consists of two congruent hubs, which have alternate nubs and pockets arranged on the front side around the circumference. They are blindly plugged into each other, axially displaced by half a nub pitch. The elastomer ring transmits the torque, in a space-saving manner, solely by compression of the elastomer, half in each hub of the coupling.
Properties:
Axial plug-in, simple to assemble
Maintenance-free
Fail-safe
Short design: minimal shaft spacing dimension
NBR spider, operating range -30° C to +80° C, temperature peaks up to +120° C
Torques up to 67,000 Nm
