Highly flexible
flange couplings in
new sizes
TR has extended the
portfolio of highly
torsionally flexible
flange couplings of the
BoWex-ELASTIC® HE
line by two sizes. The new couplings
are available in different Shore
hardnesses and suitable for high-
performance drives of up to 5,000
kW.

The BoWex-ELASTIC® HE is a flange
coupling with high torsional
flexibility consisting of a circular
elastomer. The rubber element is
made of vulcanized natural rubber
and stressed for torque-to-bore ratio.
It reduces the torsional vibrations
occurring in the drive train as well
as the cumulative forces and, due
to different elastomer hardnesses,
the flange coupling can be adjusted
to the respective application for
a resonance-free operation. The
plug-in coupling hub is designed
according to the BoWex curved-tooth
gear principle and compensates
for axial, radial and angular shaft
displacements. KTR has now
expanded the BoWex-ELASTIC® HE
line by the sizes 240 HE and 275 HE
– making the coupling suitable for
drives of up to 4,000 kW and 5,000
kW, transmitting torques of up to
32,000 Nm and 45,000 Nm. Possible
application fields are gensets, pumps
and compressors, as well as high-
performance stationary and mobile
drive systems.
Precision power transmission
When accuracy and drive positioning is paramount think ROTEX® GS. This three-
part coupling is backlash-free under pre-stress and offers varying hub designs and
Shore hardnesses to produce the optimal coupling for each application in automation
engineering. While still vibration-damping, the GS delivers optimal torsional stiffness
without consession to accuracy, even in highly dynamic servo drives.
