FLENDER RUPEX Pin and Bush Coupling

  • Damping, fail-safe pin and bush coupling for medium and higher torques
  • Nominal torque range from TKN = 200 Nm up to 1,300,000 Nm with 26 sizes
  • Temperature range: from –50 °C to +100 °C

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 optimized 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.

Examples of application

  • Mining and Cement: conveyor belts, apron conveyors, bucket elevators, tube mills, rotary kilns, bunker dischargers, vertical mills, bucket excavators, crushers, roller presses, separators, heating technology
  • Steel Production: shears, straightening machines
  • Cranes: hoisting and luffing gear systems, slewing gear systems, trolley and travel gear systems
  • Oil and Gas: pumps, fans, compressors, air condensers
  • Power Generation: pumps, fans, compressors, air condensers, generators, cooling towers, water turbines
  • Chemicals and Pharmaceuticals: pumps, fans, compressors, driers, lauter tuns, mixers, cooling towers, agitators, reactors
  • Plastics and Rubber: single- and double-screw extruders
  • Pulp and Paper: woodgrinders, waste paper, wet section, dry section, smoothers and cylinders, reel winders, coating machines, calenders, wastewater purification plants
  • Water and Wastewater: aerators, water screw pumps
  • Food and Beverage: lauter tuns, reactors, agitators, mixers
  • Sugar: generators, extraction plants, countercurrent cossette mixers, diffusers, sugar cane mills
  • Passenger Transport: cable cars

Advantages of the product

  • 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)
  • Can be used in potentially explosive atmospheres; certified acc. to 2014/34/EU (ATEX)
