ROTEX® BFN

0 - 35,000 Nm / coupling as a flange type

ROTEX BFN is a torsionally flexible elastomer coupling as a flange type (flange coupling) and particularly suitable for applications in heavy engineering.

The BFN design of the ROTEX elastomer coupling is characterized by the flange type allowing for radial assembly and disassembly of the shaft coupling or the elastomer without displacing the driving or driven side.

The flange hub 4N of the torsionally jaw coupling as a flange type ROTEX BFN is made of steel and the driving flange 3Na is made of GJS.
