Flexible element:

1 Precompressed natural rubber
2 Bonded metal spacers,
3 Precompression band (to be removed after installation).

4 Die-cast steel (except 632320 which is cast-iron).

The JUBOFLEX coupling is designed with the following features:

– Radial disassembly without moving the machines that are coupled.
– The flexible element is precompressed during assembly, which extends the range of operating conditions where the rubber is not subject to tension.


– Highly effective attenuation of cyclic irregularities and peaks in the torque.
– Very safe in use and the precompression ensures very high resistance to oscillation
– Tolerance to large misalignment: avoids the need for precise alignment of the machines to be coupled.


In use, precompression is achieved by the fixing bolts, and the JUBOFLEX coupling operates without the precompression band round the flexible element.
