Wire race bearings
Wire race bearings are a unique construction with ring-shaped raceways made of steel. They are intended for installation directly in the basic structure, which thus replaces the bearing rings in a conventional bearing.
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 rotation/balance at increased machine speeds, shorter downtime for service and increased precision means that more and more people are building in ETP hydraulic axle-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.
-
Fast, compact attachment of small components. ETP-MINI is a good alternative to wedge joints or stop screws when a backlash-free joint with adjustment possibilities is desired. Typical areas of use are 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.
Wire race bearings are a unique construction with ring-shaped raceways made of steel. They are intended for installation directly in the basic structure, which thus replaces the bearing rings in a conventional bearing.
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.
Linear controls are a system where quality and a high level of technology are hallmarks. Rails and carriages are manufactured in aluminum for the lowest weight...
