Diaphragm Couplings

Diaphragm Couplings

Highest torques are safely and reliably transmitted at the highest speed via a contoured single or multi-disk diaphragm. Power ranges of up to 150 MW can be easily accommodated matching with our high speed gear units.

RENK diaphragm couplings are maintenance-free and stand out with their years of trouble-free operation. The basic design consists of just a few components. This makes assembly and handling easier for users.
Each diaphragm coupling is designed using FEM calculation methods to optimally meet the requirements of individual customers.


  • Maximum radial rigidity
  • Low restoring and bending moments
  • Lightweight
  • Maximum balance quality
  • Few individual parts
  • Maintenance-free
  • API 671-compliant, ATEX 2014/34/EU possible
