Siemens Rupex Pin & Bush Couplings



RUPEX couplings are used as flexible compensating couplings in all applications requiring a reliable transmission of torque under harsh operating conditions. The conical seats of the buffer pins facilitate mounting and guarantee maintenance-free operation. 

The optimised shape of the barrelled buffers allows simple plug-in assembly and low circumferential backlash. Many type variants are offered, e. g. with brake disk, axial play limiting device, or brake motor couplings.

Advantages of the product

  • Flexible fail-safe pin and bush coupling for medium up to high torques
  • Compact design; low weights and mass moments of inertia
  • Independent of direction of rotation (suitable for reversing operation)
  • Suitable for plug-in assembly (blind assembly, bell housing installation)
  • Torque range of the standard series between 200 Nm and 1,300,000 Nm
  • Can be used in potentially explosive atmospheres; certified acc. to 94/9/EC (ATEX 95)

Examples of application

RUPEX couplings are used in general mechanical engineering both as high-speed couplings and for high torques, e. g. in

  • Cranes
  • Conveyors
  • Blowers
  • Screw pumps
  • Cableways
  • Mixers
  • Cement processing machines
