ETP-HYLOC is a hydro-mechanical hub-shaft connection
which, due to its robust design, is ideally suited to work in
difficult environments and heavy operations like steel rolling
mills, process industries etc.
ETP-HYLOC is fast to mount, has good concentricity and can
take high torque and radial loads. Mounting and dismantling is
easily carried out with a hydraulic pump.
<;@A?B0A6<;
ETP-HYLOC is a hydro-mechanical joint, which consists of a
double-walled steel sleeve which encloses a conical moveable
piston. Mounting and dismantling is carried out with a hydraulic
pump. In the flange there are three threaded connections (”ON”,
”P” and ”OFF”) in the radial direction and the same in the axial.
This makes it possible to choose radial or axial connection of
the pump hoses, depending on the build-in situation.
"=2?.A6<;
When the piston is moved by the hydraulic pressure from the
pump, the double-walled sleeve expands uniformly against
shaft and hub to form a rigid joint. When dismantling, the piston
is moved in the opposite direction and the joint will loosen.
<B;A6;4
Apply pressure in the ”ON” and ”P” (not shown)
connections. When mounted no hydraulic pressure
remains. The small conical angle prevents the piston
from releasing.
6@:.;A96;4
Apply pressure in the ”OFF” and ”P” (not shown)
connections. ETP-HYLOC returns to its original
measurements and the joint is loose.

Please handle ETP-HYLOC carefully when moving
or mounting/dismantling from the machine as it is a
high precision unit. Always make sure all contact
surfaces are clean and free from impurities.
Should ETP-HYLOC be difficult to handle or extract,
the extra threads in the flange could be used for
ease of handling and/or extraction.
M8/M12/M16 threads, depending on ETP-HYLOC

Never pressurise ETP-HYLOC without hub and shaft
mounted. To pressurise an unmounted ETP-HYLOC
may destroy it.

Read this Instruction manual through carefully in
order to familiarize yourself with the safe and
efficient operation of this product. Keep this
handbook for reference purposes. This Instruction
manual contains important instructions and
directives for the safe and proper operation of the
product.
*<?86;4D6A55645=?2@@B?2
All accessories that are connected to ETP-HYLOC,
such as pump, connections, hoses and other
accessories must be designed for a working
pressure that is at least equal to the maximum
pressure that is needed for ETP-HYLOC.
Do not use incorrect/faulty accessories when
working with high pressures.
Do not overtighten connections/fittings. It is better to
re-tighten if a slight leakage occurs than to damage
the threads by overtightening.
Protection glasses should be worn
at all times when
mounting/dismantling ETP-HYLOC.

ETP-HYLOC est une bague hydromécanique arbre /moyeu,
robuste par sa conception. Elle est idéale pour travailler dans
des environnements difficiles: laminoirs, process industriels.
Une des applications types est la fixation des arbres de rouleau
de convoyage. ETP-HYLOC est rapide à monter, possède une
bonne concentricité et peut supporter de forts couples et de
fortes charges radiales. Le montage et démontage se font
facilement à l’aide d’une pompe à main.
<;@A?B0A6<;
ETP-HYLOC est une bague de serrage hydromécanique
constituée d’une douille à double paroi en acier renfermant un
piston conique mobile. La flasque comporte 3 raccords filetés
(« ON », « P » et « OFF ») Les connectiques sont doublées
pour pouvoir choisir un raccordement radial ou axial.
<;0A6<;;2:2;A
Le déplacement du piston provoque, grâce à la pression
hydraulique générée par la pompe, l’expansion uniforme de la
douille à double paroi contre l’arbre et le moyeu, réalisant un
assemblage fretté. Lors du démontage le piston se déplace
dans la direction inverse et l’assemblage est libéré.
<;A.42

pression hydraulique n’existe dans le manchon.
La faible conicité du piston empêche le grippage.
