ETP-EXPRESS has only one screw for pressurising, it is therefore suitable when there is a need for the repositioning of the hub fast and accurate. The screw is tightened in the radial direction, this means no space is used along the shaft for mounting tools. Other components can be mounted on the shaft all the way up to the flange. ETP-EXPRESS has extremely small built-in dimensions.
CONSTRUCTION
ETP-EXPRESS consists of a double-walled hardened steel sleeve filled with a pressure medium and a flange. The flange part contains a screw and piston with seals to maintain pressure.
OPERATION
When the pressure screw is tightened the double-walled sleeve expands uniformly against shaft and hub and creates a rigid joint. Dismantling is done by loosening the screw. ETP-EXPRESS returns to its original dimensions and can easily be dismantled.

CONSTRUCTION
ETP-CLASSIC R is the same as ETP-CLASSIC but made of hardened stainless steel.
Type R has hex head stainless steel screws, in order to facilitate easy cleaning when used for example in machines for processing food.
OPERATION
ETP-CLASSIC R works in the same way as ETP-CLASSIC with a few exceptions:
FEATURES & BENEFITS
ETP-MINI is superior to keyways or setscrews because it allows an adjustable, backlash free joint. Typical applications are mounting of hubs on small electrical motors, stepmotors and encoders. As no keyways are needed, the shaft will not be weakened and the unbalance will be lower, which is very important at high speeds, as the motor bearing is sensitive to vibrations. Also available in stainless, ETP-MINI R, suitable for the food processing industry etc.
CONSTRUCTION
ETP-MINI consists of two, partly slotted, conical steel sleeves (type R stainless) and clamping screws (type R stainless).
OPERATION
By tightening the screws the inner sleeve is pressed against the shaft and the outer sleeve against the hub thus forming a rigid joint.
When dismantling, one or if necessary, two of the screws are moved to the threaded dismantling holes in the flange. By tightening, the sleeves will separate and the joint will loosen.
ETP-MINI R has one screw more than the normal ETP-MINI in order to transmit the same torque (lower tightening torque for stainless screws). The built-in dimensions are the same.
FEATURES & BENEFITS
ETP-HYLOC, due to its robust design, is ideally suited to work in difficult environments and heavy operations like steel rolling mills, process industry etc. An interesting application, among many, has been fastening of rolls to shafts. ETP-HYLOC is fast to mount, has good concentricity and can take high radial loads.
CONSTRUCTION
ETP-HYLOC is a hydromechanical joint, which consists of a double-walled steel sleeve, which encloses a conical moveable piston. 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 hoses. Mounting and dismantling is carried out with a hydraulic pump with three hoses.
OPERATION
When the piston is moved, by the hydraulic pressure from the pump, the double-walled sleeve expands uniformly against shaft and hub and forms a rigid joint.
When dismantling, the piston is moved in the opposite direction and the joint will loosen.
A small amount of oil will be taken via spiral tracks in the piston between the surfaces, in this way making it easier for the piston to move.
FEATURES & BENEFITS
ETP-HYCON S and SX are compact rigid shaft-shaft couplings for high performance, quick mounting/dismantling and thus short downtime. Type SX is longer than S and can transmit considerably higher torque. Both types are type approved by DnV for marine applications.
CONSTRUCTION
ETP-HYCON S and SX both consists of an outer sleeve with hydraulic connections, an inner sleeve with ETP-HFC on the inside and an on the inner sleeve assembled cylindrical ring and seals.
OPERATION
When mounting two connections are pressurized simultaneously. The oil pressure lubricates the contact surfaces in the axial space between the seals. This facilitates the movement of the outer sleeve, which is forced to move because of the axial force created by the oil pressure. When the outer sleeve has been driven up a certain length, the pressure is released, the outer sleeve compresses the inner sleeve to an even surface pressure. A rigid strong joint has been created.
Dismantling is done in the same way, but with a lower pressure to get an even dismantling process.
FEATURES & BENEFITS
The unique ETP-HFC treatment which increases the friction considerably, the hydro-mechanical principle and the through seals closed oil chambers together gives a great number of advantages:
ETP-HYCON F and FX are compact rigid shaft-flange couplings for high performance, quick mounting/dismantling and thus short downtime. Type FX is longer than F and can transmit considerably higher torque. Both types are type approved by DnV for marine applications.
CONSTRUCTION
ETP-HYCON F and FX both consists of an outer sleeve with hydraulic connections, an inner sleeve with a flange and ETP-HFC on the inside and an on the inner sleeve assembled cylindrical ring and seals.
OPERATION
When mounting both two connections are pressurized simultaneously. The oil pressure lubricates the contact surfaces in the axial space between the seals. This facilitates the movement of the outer sleeve, which is forced to move because of the axial force created by the oil pressure. When the outer sleeve has been driven up a certain length, the pressure is released and the outer sleeve compresses the inner sleeve to an even surface pressure to the shafts. A rigid strong joint has been created.
Dismantling is done in same way, but with a lower pressure to get an even dismantling process.
FEATURES & BENEFITS
The unique ETP-HFC treatment which increases the friction considerably, the hydro mechanical principle and the through seals closed oil chambers together gives a great number of advantages:
We have, through the development of ETP-OCTOPUS, explored the many positive qualities of our hydraulic hub-shaft connections. The most important features are compact design, quick locking, accurate positioning and good runout. The joint will not damage the contact surfaces and must be easy to dismantle.
For ETP-OCTOPUS the pressure setting is done with an external pressure source separate from the clamping joint. This makes the pressure setting extremely fast and makes it possible to pressurize several joints simultaneously and remotely.
CONSTRUCTION
ETP-OCTOPUS is a double-walled hardened steel sleeve with a flange. In the flange there are bores for mounting of a hub and a scraper with a screw joint, threaded connection for hydraulic oil and an air relief screw. The inner diameter has spiral tracks in order to get an even friction and a defined locking force.
OPERATION
The assembly is done with the screw joint. When hydraulically pressurized the inner sleeve expands uniformly against the shaft and creates a rigid joint. When the pressure is released the sleeve returns to its original dimension and can easily be moved along the shaft to its new position and be repressurized.
FEATURES & BENEFITS
The unique hydraulic principle, the solid and simple design of the sleeve gives a great number of advantages:
ETP-HYDROPRESS - Quick and precise fastening for larger shafts
ETP-HYDROPRESS is available on request.
The dimensions and loads in the list below serve as guidelines to make a customized product. It can be made for both larger and smaller shafts as well as shorter or longer. Number of mountings > 1 000.
For extreme high torque applications the contact surfaces of ETP-HYDROPRESS (sizes ≥130 mm) can
be plated with ETP-HFC, High Friction Coating, which doubles the torque capacity. For frequent sliding along a shaft it can be plated on the inside with aluminium bronze.
Construction
ETP-HYDROPRESS is a hydraulic joint, which consists of a double-walled steel sleeve. Mounting is easily carried out with a hydraulic grease pump. In the flange there are two connections:
a grease nipple for the pump and a pressure release valve used for dismantling, a screw which presses against a steel ball and forms a spherical seating. Radial and/or axial connections for the pump hoses are possible. The inner diameter can be made with spiral tracks in order to easier let foreign liquids or particles disappear.
Operation
When the hydraulic pressure from the pump is injected, the double-walled sleeve expands uniformly against shaft and hub and along the shaft and forms a rigid joint. When dismantling, the allen screw in the pressure release valve is loosened and the grease comes out. ETP-HYDROPRESS returns to its original measurements and the joint is loose. Normal working pressure is up to 700 bar.
FEATURES & BENEFITS
OPERATION
The Knifeholder, ETP-KN, consists of a double-walled hardened steel sleeve filled with a pressure medium. The pressurising mechanism consists of a screw and piston with double sealing function.
