Highly flexible ELPEX-B couplings 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.
Instead of the standard rubber tire, a chloroprene rubber tire is available. This option is labeled FRAS, i.e. fire-resistant and anti static.
