BoWex-ELASTIC® HE-ZS(HEW-ZS) highly flexible flange couplings

The coupling type BoWex ELASTIC HE-ZS / HEW-ZS is a highly flexible flange coupling for mounting to I. C.-engines and electric motors.

This type combines the standard flange connection acc. to SAE-J 620 and drop-out center pieces for pump drives.

These drop-out center pieces are available in customized lengths. The HE-ZS / HEW-ZS is applicable up to a maximum operating temperature of 100 °C.  

The flange coupling is assessed and approved for potentially explosive atmospheres acc. to EC directive 2014/34/EU. The drop-out center pieces can be combined with coupling type HE and HEW and allow for radial disassembly 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.

  • Various kinds of Shore hardness
  • Torsional vibration analyis
  • Supercritical selection
  • Temperature resistance (enabling higher temperatures via EPDM)
