Due to the hydraulic working method, the ETP principle provides a number of important advantages for the customer: compact design, quick assembly, easy to position, good rotation, does not damage the contact surfaces and is easy to dismantle.
These qualities are important today and will become even more important in the future. Increased requirements for smaller installation dimensions, better roundness/balance at increased machine speeds, shorter downtime for service and increased precision means that more and more people are installing ETP hydraulic shaft-hub connections.
The original
The original – a competitive connection for all normal needs. ETP-CLASSIC consists of a double-walled sleeve of hardened steel filled with a specially adapted pressure medium, sealing ring, piston, pressure ring and clamping screws.
Also available to order in stainless steel (Classic R).

-
High precision and frequent assembly. ETP-TECHNO is especially suitable for applications where quick frequent changes or adjustments with high precision are needed, can be assembled and disassembled 1000s of times.
-
Compact fastening of small components. ETP-MINI is a good mechanical alternative to key joints or set screws when a backlash-free joint with adjustment options is desired. Typical applications include mounting hubs on small electric motors, stepper motors and encoders.
-
Fast assembly and high radial loads! With ETP-POWER, all the positive advantages and characteristics of hydraulic clamping are combined with high radial load capacity due to the specific characteristics of the pressure medium.
-
ETP-HYLOC is a hydromechanical hub-shaft coupling which, thanks to its robust design, is ideal for working in harsh environments and heavy operations such as steel rolling mills, process industries, etc. One interesting application, among many, has been the attachment of feed or form rolls to shafts.

The hydraulic connection ETP-OCTOPUS is suitable when the repositioning of machine parts must be done frequently,
quickly and with high precision along the axis, for example in machine tools for qualified processing or shaping of steel.
Due to the hydraulic working method, the ETP principle provides a number of important advantages for the customer: compact design, quick assembly, easy to position, good rotation, does not damage the contact surfaces and is easy to dismantle.
Slewing bearing is a wire bearing that is fitted with an inner and outer ring. The advantage of this system is i.a. that the outer and inner ring can be made of materials other than steel – eg aluminum for light weight.
Direct drive bearing units are suitable for applications where high performance and low space requirements are important criteria.
