Learn more →Flexible couplings transmit force reliably, even where shaft misalignment cannot be avoided in general mechanical engineering. The elastic elements are torsionally flexible and shift critical torsional vibrations out of the operating range. Their high material damping absorbs plant-induced shocks, critical speed ranges can be traversed and resonance amplification remains limited. REEL has manufactured this programme since 1950, Made in Germany.
Flexible Couplings · ELBO-R pin coupling A flexible coupling connects two shaft ends and compensates angular, radial and axial misalignments. The torsional flexibility of the elastic elements shifts critical vibrations, damps torque shocks and protects bearings and machine components. The right coupling type depends on torque, speed, misalignment and installation conditions. We size the correct type for your application.
Detail · Elastic buffers of the ELBO-R REEL offers flexible couplings in several designs. Choose the right type and see the details on the relevant product page.
The ELBO-R flexible pin coupling is the flagship of the REEL programme. It transmits torque via elastic pins, damps shocks, compensates shaft misalignment and is fail-safe up to the shear torque of the metal parts. Pins and buffers can be replaced without moving the motor or machine axially.
Flexible pin coupling from the ELBO series, in 39 sizes for 180 to 540,000 Nm.

Also aluminium Flexible annular gear coupling. The only series in the programme also available in aluminium.
To product pageBesides the standard version, the ELBO-R is available in special designs combined with a brake, a freewheel or an axial play limiter. All variants are supplied on request.
Limits the axial play between the two coupling halves.
Brake disc that holds the drive at standstill.
Brake disc that brakes the drive during operation.
Brake disc and axial play limitation in one coupling.
Coupling and brake drum as one unit.
Roller freewheel in the hub: transmits torque in one direction of rotation and overruns in the other.
Version with a divided hub.
Material and design are selected according to your application. The hubs of the standard version are made of grey cast iron or steel; further materials are available for special versions. Pins and elastomers depend on the coupling type.
Hubs for general mechanical engineering.
Hubs for special requirements regarding strength and corrosion resistance.
Pins, buffers, flexible packs and gear rings.
Aluminium is available for the ZARIFLEX, the only series in the programme with an aluminium version.
You know the application, we know power transmission. Tell us torque, speed, shaft diameter and misalignment, and we will find the right coupling type.
With these four parameters we recommend the right type.
