BRAND : ETP
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!

Construction
ETP-OCTOPUS is a hydraulic connection which consists of a double-walled
hardened steel sleeve with a flange.
In the flange there are bores for mounting of a hub and a scraper with a screw
joint, threaded connection for hydraulic oil and an air relief screw.
The inner diameter has spiral tracks in order to get an even friction and a
defined locking force to the shaft.
Operation
The assembly of the hub is done with the screw joint. When hydraulically
pressurized the inner sleeve expands uniformly against the shaft and creates a
rigid joint.
The sleeve does not expand to the outside.
When the pressure is released the sleeve returns to its original size and can
then easily be moved along the shaft to its new position and be re-pressurized.
