Flender highly flexible couplings are well-suited to connect asymmetrically operating machines. They are used preferably in periodically stimulated systems. Highly flexible, backlash-free tire coupling – Nominal torque range from TKN = 1,600 Nm up to 90,000 Nm with 9 sizes – Temperature range: from –40 °C to +80 °C
Flexible and adaptable
Owing to its low torsional stiffness and damping properties the Flender highly flexible couplings are very well suited to connecting machines with considerably non-uniform torque characteristics. Types with a fail-safe device between the flexible rings ensure emergency operation if the flexible rings are destroyed.

Highly flexible, backlash-free tire coupling – Nominal torque range from TKN = 24 Nm up to 14,500 Nm with 15 sizes – Temperature range: from –50 °C to +50 °C for natural rubber materials, from –15 °C to +70 °C for chloroprene rubber
Flexible and adaptable
Flender highly flexible couplings ELPEX-B transmit torques without circumferential backlash in machines with non-uniform torque characteristics. They are resistant to wear and maintenance-free. The hubs of the ELPEX-B couplings are made of high-quality cast iron or steel. The torque is transmitted by a flexible tire reinforced with a cord ply.

Highly flexible rubber disk coupling to connect machines with high torque fluctuations – Nominal torque range from TKN = 330 Nm up to 63,000 Nm with 17 sizes – Temperature range: from –40 °C to +120 °C
Flexible and adaptable
Owing to its low torsional rigidity and damping properties the Flender highly flexible couplings ELPEX-S are very well suited to connecting machines with considerably non-uniform torque characteristics. The inside diameter of the rubber disk element is vulcanized on a flange. ELPEX-S couplings are designed as a flange/shaft connection or shaft/shaft connection as standard. The hub can take a taper bush.
