High-quality solutions for your plant

A wide variety of N-EUPEX® types offer optimum coupling solutions for every challenge. Couplings with a double-cardanic design, with torque limiter, with clamping element or short design enrich the extensive modular system of pin couplings. The flexible modular system provides sustainable options that optimize machines and systems and reduce maintenance. A high combination diversity and flexibility is ensured by diverse components.

 

Robust and proven a million times

Due to their torsional flexibility, N-EUPEX® couplings can move critical torsional vibrations away from the operating area of 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 (NBR) are available in different degrees of hardness for many applications. In addition, elastomers made of thermoplastic polyurethane (TPU) and of NBR with fabric inserts for increased load-bearing capacity are offered. Metal pins and flexible elements are designed so that no wear occurs when they are properly fitted.

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.
