Pascal discovered the principle We put it to work The scientist Blaise Pascal formulated the principle of pressure propagation in liquids many years ago. ETP has explored the many positive qualities in this principle, developed it further and applied it to hub-shaft connections. A hydraulic pressure medium confined in a double-walled sleeve is pressurized, with screws or with an external pump.The double-walled sleeve expands uniformly and gives an even contact pressure against shaft and hub. With increasing requirements on down sizing of machines, better runout/balance, increased...

ETP hub-shaft connections are today regarded as the natural range to choose from for professional machine design. They represent the optimal cost/ performance ratio and are available in a number of variants.They operate according to either the hydraulic or hydromechanical principle, which gives unique advantages when designing, in operation and when dismantling. Quick mounting. Easy and accurate to position. Saves space along the shaft. Good runout. The hydraulic ETP principle ETP-EXPRESS, ETP-EXPRESS R, ETP-POWER and ETP-TECHNO are all mounted very quick and simple by tightening of only...

The hydromechanical ETP principle ETP-HYLOC is mounted quickly and easily, even for big shafts, with a hydraulic pump. The hydraulics makes the mounting simple and gives a good runout. When the connection is mounted it is mechanically self locked. The hydromechanical ETP principle is specially suitable for high torque, high radial forces and for big shafts. Quick mounting and dismantling. High torque, radial and axial forces. Good runout. Connection axial and/or radial.

hydraulic connection which has only one screw for pressurising. It is especially suitable for repositioning of the hub fast and accurately. 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 which makes a compact design possible.

Easy to position and adjust with one screw In this handling and packaging machine for newspapers after printing, ETP-EXPRESS of various sizes are used. The final adjustment of levers and timing pulleys in order to get all parts synchronised is facilitated, as only one screw needs to be loosened/tightened. The radial access to the screw permits a compact design. Also hubs of aluminium and cast iron can be used because of the moderate surface pressure. Good runout and radial accessibility This unit belongs to a production line which inserts enclosures into newspapers after printing and...

Radial tightening When fastening the drive wheels for a number of synchronised transport chains, often the space along the shaft is limited. In this case it was solved with ETP-EXPRESS, as only radial access to the screw is needed. Only one screw per connection makes necessary adjustments after assembly easier. Synchronisation In transport equipment often a number of drives needs to be synchronised. In this machine ETP-EXPRESS is used for this purpose for both the chain and timing pulley drives. The simple mounting and radial access were the reasons. The compact built-in dimensions are also...

ETP-EXPRESS is available as standard for shafts 15-100 mm, also imperial. Runout ≤ 0,02 mm. Number of mountings 500 - 2 000 (size dependent). The extremely thin built-in dimensions allows for a compact design with low weight and inertia. Construction ETP-EXPRESS is a hydraulic connection which consists of a double-walled hardened steel sleeve filled with a pressure medium and a flange. The flange part contains 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...

Corrosion resistantand easy to clean The demand from the food and ; * u process industries is increasing for stainless steel hub-shaft connections. The most common sizes of the hydraulic connection ETP-EXPRESS are available in stainless steel. The flat flange design allows for easy cleaning, essential within food processing. Also the pressure medium and screw lubricant are approved for use in the food industry.
