ETP-CLASSIC is available as standard for shafts 15-100 mm, with imperial sizes and a short overall length version (type S) also available . Also available in stainless steel (type R). Typical runout is : 0,03 – 0,06 mm. Number of mountings: 100 (type R: 50). The small number of clamping screws with low tightening torque, makes the mounting/dismantling procedure fast and easy.

Construction

ETP-CLASSIC is a hydraulic connection which consists of a double-walled hardened steel sleeve, filled with a specially developed pressure medium, sealing ring, piston, pressure flange and cap head clamping screws.

Construction

ETP-CLASSIC R is the Stainless Steel version of ETP-CLASSIC. It is a hydraulic connection which consists of a double-walled hardened steel sleeve, filled with a specially developed pressure medium, sealing ring, piston, pressure flange and cap head clamping screws. ETP-CLASSIC type R is made of stainless steel and has hex head stainless steel clamping screws. This in order to facilitate easy cleaning, making it ideal for food processing applications.

Operation

When tightening the screws, the sleeve expands uniformly against hub and shaft and creates a rigid joint.

ETP-MINI is available as standard for shafts 6-14 mm, with imperial sizes also available. Run out ≤ 0,02 mm. Number of mountings 100 (size dependent). The ETP MINI has an extremely compact design with low weight and inertia.

Construction

This is a simple mechanical connection consisting of two partly slotted, conical sleeves and cap head clamping screws.

Operation

By tightening the cap head screws,cuases the inner sleeve to be pressed against the shaft and the outer sleeve against the hub.

ETP-EXPRESS is available as standard for shafts 15-100 mm, with imperial sizes also available. Runout ≤ 0,02 mm. Number of mountings 500 – 2000 (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 stainless steel sleeve filled with a pressure medium, and a flange. The flange part contains a stainless screw and piston with seals to maintain pressure.

ETP-EXPRESS R is the Stainless Steel version of ETP-EXPRESS. It is available as standard for shafts 15-80 mm, with imperial sizes also available. Runout ≤ 0,02 mm. Number of mountings 200 – 800 (size dependent). The extremely thin built-in dimensions allows for a compact design with low weight and inertia.

Construction

ETP-EXPRESS R is a hydraulic connection which consists of a double-walled hardened stainless steel sleeve filled with a pressure medium, and a flange. The flange part contains a stainless screw and piston with seals to maintain pressure.

ETP-POWER is available as standard for shafts 15 – 40 mm. Run out ≤ 0,03 mm. Number of mountings 200 - 500 (size dependent). ETP-POWER combines quick mounting with a high radial load capacity due to the specially developed pressure medium. As the name suggests, ETP POWER is for higher torque applications.

Construction

ETP-POWER is a hydraulic connection which consists of a double-walled hardened steel sleeve filled with a specially developed pressure medium and a flange. The flange part contains screw and piston with seals to maintain pressure.

ETP-TECHNO is available as standard for shafts 15-130 mm, with imperial sizes also available. Run out ≤ 0,006 mm. Number of mountings 500 – 5000 (size dependent). The extremely thin built-in dimensions allows for a compact design with low weight and inertia.

Construction

ETP-TECHNO is a hydraulic connection which consists of a double-walled hardened stainless steel sleeve filled with a pressure medium, and a flange. The flange part contains a stainless screw and piston with seals to maintain pressure.

ETP Hydraulic Bushes

Pascal discovered the principle. ETP put it to work. ABSSAC is proud to announce that it is now the appointed United Kingdom Distributor for the entire product range of ETP hydraulic clamping hubs and bushes. The scientist Blaise Pascal formulated the principle of pressure propagation in liquids many years ago: Pascal's law or the principle of transmission of fluid-pressure states that , ”pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure ratio (initial difference) remains the same”. The ETP product utilises the many positive qualities of this principle and has continued to develop it further so that it can be utilised reliably and accurately within industrial applications.

All ETP products consist of a double-walled hardened steel (in some cases stainless steel) sleeve, filled with a pressure medium. In the product flange there are one or more screws and a piston with seals for the pressure setting. When the pressure screw is tightened an even and moderately high surface pressure is created against the shaft and hub, causing the locking effect. The self-contained product allows this procedure to be repeated many times.

Whether the hubs are to be removed or repositioned, mounting and dismantling is done in less than a few seconds. The hydraulic principle gives immediate advantages for today´s modern machines. The compact designs also ensure better concentricity and balance at increased machine speeds, shorter downtime for service and increased precision. The ETP products now available through Abssac Limited are chosen for more and more mechanical designs.


So what is available ? - Hydraulic Hub-Shaft connections – Quick, easy and precise screw mounting.

With names like ETP Express, ETP Express R, ETP Power and ETP Techno, these products are, as it sounds, designed for a multitude of applications. In each case only a single screw is used for mounting and dismounting of the hub. This simple feature ensures an extremely quick and easy service interval time and incredibly easy adjustment or repositioning of the hub. The single screw hubs are used in a variety of applications and industries such as packaging, food, beverage and pharmaceutical. The standard ETP-Techno and ETP-Express  are available for shafts 15mm to 130mm. ETP-Express R, Stainless steel versions, are available to suit shafts from 15mm to 80mm.
