BoWex-ELASTIC® HE3(HE4)HE-D highly flexible flange coupling

The coupling type BoWex ELASTIC HE3/HE4 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 steel available in 16 coupling sizes and ten SAE flange sizes. 

The mounting flange made of steel allows for reducing the elastomer thickness by 10 mm resulting in a severely compact design.  The flange coupling HE3/HE4 is applicable up to a maximum operating temperature of 100 °C.

The combination with the coupling hubs of the BoWex standard range allows to compensate for misalignment of driving and driven side. The flange coupling is assessed and approved for potentially explosive atmospheres acc. to EC directive 2014/34/EU.

Type HE-D is a special version with double arrangement of elastomers to double the torques. Differentiating between the respective type 3 and 4 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.
