The ELPEX-B Rubber Tire Coupling, developed by Flender, is a highly flexible, backlash-free power transmission component engineered for machines with non-uniform torque characteristics[1]

Constructed with precision, the coupling consists of high-quality cast iron or steel hubs and a flexible tire reinforced with cord ply, which facilitates torque transmission[

A core advantage is its ability to compensate for large axial, radial, and angular shaft misalignments, making it suitable for flexibly mounted machines[1][

The chloroprene rubber tire variant is FRAS-certified (fire-resistant and antistatic), expanding its use in harsh environments with oil or grease contact[

Common applications include crushers, mixers, mills, air condensers, wastewater purification plants, and reactors, as well as mining and cement industry equipment[2

Flexible and adaptable

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.

Your benefits at a glance

• Compensation of very large shaft misalignments
• Independent of direction of rotation (suitable for reversing operation)
• The rubber tire can be replaced easily without the need to move the coupled machines
• Easy mounting on the shafts is possible with taper bushes

Did you know?

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