BoWex-ELASTIC® HE1(HE2) highly flexible flange couplings

The coupling type BoWex-ELASTIC HE1/HE2 is a highly flexible flange coupling with SAE and special flange dimensions for mounting to I. C.-engines.

The design is characterized by a mounting flange made of polyamide available in five coupling sizes and six SAE flange sizes. The flange coupling HE1/HE2 is applicable up to a maximum operating temperature of 100 °C.

The combination with coupling hubs of the BoWex standard range allows for compensating for misalignment of driving and driven side. The coupling is assessed and approved for potentially explosive atmospheres acc. to EC directive 2014/34/EU. Differentiating between the respective type 1 and 2 results in an either short or long version of the coupling.

For drives subject to severe torsional vibrations for flexible torque transmission in the combination of a diesel engine with splitterbox, generator, compressor, feed pump or high-pressure pump, etc.:

The BoWex-ELASTIC flange coupling consists of a highly flexible, circular rubber element made of natural rubber stressed for torque-to-bore ratio. The internal axial plug-in hub component with the external spline corresponds to the BoWex® basic type. The BoWex-ELASTIC is available in various kinds of elastomer hardness with mounting flanges on the engine side acc. to SAE J620 and with special dimensions for a power up to 5,000 kW.
