It’s a known problem with electric motors; bearings fail prematurely
due to misalignment and vibration, causing downtime and increased
maintenance costs. Choose quality to reduce these failures by half……
Insist on a KTR coupling. Any pump to any motor, we’ve got a coupling
to suit the job and our split hub ROTEX® and BoWex® designs offer
one of the quickest maintenance turnarounds in the industry!

KTR: Backlash-free shaft
coupling with integrated
clamping system
I
n cooperation with the
Swedish company ETP,
KTR developed a backlashfree servo coupling with an
integrated clamping system. The
highlight is that the coupling can be
mounted with one screw only which is
completed within a few seconds.
ROTEX® GS with integrated ETP
clamping system
ROTEX® GS has been integrated
with the ETP clamping system in a
collaborative effort between KTR and
the Swedish company ETP Transmission
AB, specialist suppliers of shaft-hubconnections utilising Blaise Pascal’s
principle of pressure propagation in
liquids. The new backlash-free and
highly accurate ROTEX® GS ETP is
made entirely of steel and specifically
suitable for applications involving highspeed drives.
The clamping system of this new
coupling type consists of a doublewalled, hardened steel sleeve that is
filled with a pressurizing medium. The
flange comprises a piston with a gasket
and a screw which is tightened on the
piston for pressure generation.
on a two-part type which will allow for
the use of other coupling types and
materials.

The screw is tightened radially, while
no axial space for assembly tools is
required. When under pressure, the
sleeve expands generating a uniform
surface pressure against shaft and
hub. This principle of just a single
screw allows for assembly within a few
seconds and ensures a continuously
variable positioning of the coupling.
The uniform stress distribution in
the basic body of the hub results in
an accurate concentricity of the ETP
system while achieving a very smooth
running result.
Currently KTR and ETP are working
