ELPEX Flexible Ring Coupling: Backlash-free, damping for uneven torque and large misalignment.
The ELPEX Flexible Ring Coupling, developed by Flender, is a highly flexible, backlash-free power transmission component engineered for machines with significantly non-uniform torque characteristics
Constructed with precision, the coupling features hubs made of grey cast iron or steel, paired with flexible rings made from a natural rubber blend reinforced with multi-ply fabric lining[5]
A core advantage is its split flexible ring design, which allows easy replacement without moving coupled machines, significantly reducing maintenance downtime[1]
The coupling is suitable for high dynamic loads and reversing operations, with progressive torsional stiffness that stabilizes performance as load increases[
Common applications include drives with internal combustion engines, piston compressors, and pumps, as well as mining and cement industry equipment like tube mills, crushers, and vertical mills[1]
Owing to its low torsional stiffness and damping properties the ELPEX® coupling is 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.

For drives subject to high shock loads or large shaft misalignments, for example in

The ELPEX coupling’s transmission characteristics are determined essentially by the flexible rings. These flexible rings are manufactured from a natural rubber blend with a multi-ply fabric lining. They are split so that they can be changed without having to move the coupled machines.
