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
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.
