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!

Structure

The ETP-OCTOPUS® establishes a hydraulic connection consisting of a double-wall, hardened steel sleeve with a flange. The flange contains bore holes for fastening the hub and wiper, the connection thread for the hydraulics and the bleed thread. The inner diameter has helical slots to maintain uniform friction and guarantee the clamping force.

Function

Fastening is carried out with screws. Due to the hydraulic pressure build-up, the inner sleeve presses evenly against the shaft – but not against the hub – thus creating a firm connection. No expansion against the hub occurs. After depressurisation, the sleeve returns to its initial state and the shaft can be repositioned and clamped.

Further information can be found in our flyer and in our catalogue.

We would be more than happy to work with you to develop the optimum solution for your specific application.

• Pressure build-up is ensured with an external pressure source. Several connections can be clamped or released simultaneously. 
• No hub is required to install the ETP-OCTOPUS® since the outer sleeve has a sufficient wall thickness to accommodate the hydraulic pressure.
