ELBO-B couplings are used in all applications requiring
an absolutely reliable transmission of torque.

Wide range of applications
ELBO-B couplings cover a wide range of requirements.
Available in 26 different sizes, couplings are available for
a range of torques extending from 120 to 450,000 Nm.
With the different variants of the individual sizes, a
finer torque gradation is achieved. This is realized via
the different number of bolts in the coupling. There are
up to three variants for every size.

Torsionally flexible and vibration damping
EL BO-B couplings damp torque impacts and allow
shifting of critical speeds.

Low maintenance
Assuming correct coupling design and correct
alignment at assembly, the buffers which are subjected
only to compression during torque transmission, have
a long life.

Easy to install
The buffers in the ELBO-B couplings can be pushed
into position. Both bolts and buffers can be replaced
without any axial movement of the motor or machinery.
Uncoupled machinery can be radially dismantled.

ELBO-B couplings are fail-safe up to the shear torque
of the metallic parts which is many times the
permissible impact torque. They therefore offer the
greatest possible operational reliability.

Angular, radial and axial flexibility
Angular, radial and axial shaft displacements can be
balanced as required.

Independent of the direction of rotation
EL BO-B couplings can be used for both directions
of rotations and are therefore suitable for reversing
