ETP stand for Energy Transfer Products Made in Sweden since 1973 to develop, manufacture, market and sell fastening and centering products based on hydraulic and hydro-mechanical principles. For use as hub-shaft connections, tool and work piece holders and similar applications. ETP Transmission AB have developed and manufactured hydraulic hub-shaft connections for more than 40 years.
ETP Keyless Bushings
ETP bushes work by creating a hydraulic pressure that expands in the thin-walled cylinder and grips both the shaft and the component at the same time - without the need for keys and keyways. This design eliminates many of the problems associated with traditional hub-shaft connections, such as machining precise keyway, quicker and frequent assembly and dismantling.
ETP-CLASSIC
ETP-CLASSIC is used in a large variety of applications, for mounting timing belt pulleys, cam curves and arms etc. Positioning along and around the shaft is easy and fast with high precision. Service and maintenance are also quick because of the easy dismantling. ETP-CLASSIC is recommended for all normal needs. ETP-CLASSIC is also available in stainless, type R, suitable for the food and medical industries.
ETP-EXPRESS
ETP-EXPRESS is a 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.
ETP-TECHNO
ETP-TECHNO is a hydraulic connection with very high precision. It is especially designed for applications where fast frequent changes or adjustments, with high precision are needed. It can be mounted/dismantled 1000´s of times. ETP-TECHNO is very easy to mount with only one screw, and it also has extremely good concentricity and is the one to choose among the ETP hub-shaft connections when very high precision is needed.
ETP-POWER
ETP-POWER is a hydraulic connection with the highest performance among the single screw ETP hub-shaft connections. With ETP-POWER all the positive benefits and features of hydraulic clamping, such as easy handling, compact design and precision, is combined with high radial load capacity due to the specific properties of the pressure medium.
ETP-MINI
ETP-MINI is a mechanical connection which is the best choice for mounting small components quick and easy. Far superior to keyways or setscrews as it gives an adjustable, backlash free joint. ETP-MINI is also available in stainless, type R, suitable for the food and medical industries!
ETP-HYLOC (For heavy loads and quick mounting)
ETP-HYLOC is a hydro-mechanical hub-shaft connection which, due to its robust design, is ideally suited to work in difficult environments and heavy operations like steel rolling mills, process industries etc. An interesting application, among many, has been fastening of feeding or forming rolls to shafts. ETP-HYLOC is fast to mount, has good concentricity and can take high torque and radial loads. Mounting and dismantling is easily carried out with a hydraulic pump.
ETP-OCTOPUS (For fast, frequent and accurate linear positioning)
The hydraulic connection ETP-OCTOPUS is suitable when repositioning of machine parts are going to be done frequently, fast and with high precision along the shaft, for example in machine tools for qualified machining or forming of steel. With the use of an external hydraulic pressure source one or several connections can be clamped or loosened simultaneously!
