Highly flexible flange couplings BoWex-ELASTIC by KTR Systems GmbH

BoWex-ELASTIC® highly flexible flange couplings

The flange couplings BoWex-ELASTIC are highly flexible couplings combining the benefits of the renowned BoWex system with the elasticity of a highly flexible coupling in a compact design.

Torsional vibrations and shock loads that arise are damped and reduced. The BoWex-ELASTIC flange couplings consist of a highly flexible, circular rubber element made of temperature-resistant natural rubber stressed for torque-to-bore ratio and an axial plug-in BoWex curved-tooth® coupling hub.

The connection of I. C.-engine and, for example, directly driven generators or mobile compressors is made by a flange coupling. It must comply with a number of specifications, while it must primarily transmit the power reliably enabling the machine to perform the pending tasks as requested.
