FLENDER N-EUPEX Pin Coupling

Damping shaft coupling that can be used universally to compensate for shaft misalignment
Nominal torque range from TKN = 19 Nm up to 62,000 Nm with 23 sizes
Temperature range: from –50 °C to +100 °C

Due to their torsional flexibility N-EUPEX couplings offer the possibility of moving critical torsional vibrations from the operating area of the mechanical equipment in such a way that no negative effects on the drive train are to be expected. N-EUPEX couplings are made of high-quality cast iron. The flexible elements made of synthetic rubber (buna N) are available in different degrees of hardness for many applications. Metal pins and flexible elements are so designed that no wear occurs when properly fitted.

Advantages of the product

Torsionally rigid and damping pin coupling to be used universally for compensating shaft misalignments
Maximum operational reliability, since fail-safe
Suitable for plug-in assembly and simplified replacement of elements in the type consisting of three parts
Dynamic adaptation by selection of elastomer hardness
Torque range from 19 Nm up to 62,000 Nm for 23 sizes and 10 different types
Can be used in potentially explosive atmospheres; certified acc. to nach 2014/34/EU (ATEX)
High degree of availability of parts ex stock

Did you know?

Original FLENDER® elastomers ensure the optimal operation of your system. The flexible elements of the N-EUPEX coupling are subject to compression. If the flexible elements are irreparably damaged, the hub parts come into contact with metal. This “emergency operation capability” is required, e.g., in the case of fire pump drives.
