ELPEX-S Rubber Disk Coupling

  • Highly flexible rubber disk coupling to connect machines with high torque fluctuations
  • Nominal torque range from TKN = 330 Nm up to 63,000 Nm with 17 sizes
  • Temperature range: from -40 °C to +120 °C

Flexible and adaptable

Owing to its low torsional rigidity and damping properties the ELPEX-S coupling is very well suited to connecting machines with considerably non-uniform torque characteristics. The inside diameter of the rubber disk element is vulcanized on a flange. ELPEX-S couplings are designed as a flange/shaft connection or shaft/shaft connection as standard. The hub can take a taper bush.

Your benefits at a glance

  • Insulates torsional vibrations with linear torsion spring characteristics
  • Many kinds of flange connection are possible (including SAE)
  • Easy plug-in assembly even for mounting positions that are difficult to access
  • Types are available where the rubber disk element can be replaced without the need to move the coupled machines
  • Overload protection for the motor and the driven machine
  • Suitable for use in potentially explosive environments; certified according to 2014/34/EU (ATEX)

Made in Germany, worldwide in use

Used in general mechanical engineering; especially suitable for drives comprising internal combustion engines, comprising piston compressors, and for cement mills.

Moreover suitable for:

  • Mining and Cement: tube mills, vertical mills, crushers
  • Steel Production: shears, straightening machines, reversing rolling mills, pilger rolling mills
  • Sugar: sugar cane mills

Did you know?

Since the different rubber versions enable the torsional stiffness to be adjusted to meet requirements, the coupling is also suitable for drives which require a specific and preferably precalculated torsional vibration behavior setting.
