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.

  • Highly flexible flange coupling for mounting to I. C.-engines and electric motors with drop-out center piece for pump drives
  • Elastomer parts available in the hardness T40, T50 and T65 Shore A
  • Compensating for high misalignment
  • Type HE-ZS with flange connection acc. to SAE-J 620
  • HEW-ZS for shaft-to-shaft connection
  • Taper and inch bores

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)
