Hydraulic and hydromechanical locking bushes

Effortlessly establishing the perfect connection

Pascal discovered the principle - ETP conducted further research on its positive properties, developed it further and made it suitable for use in shaft-hub joints.

"A fluid that is sealed in a container and is subjected to pressure distributes the pressure uniformly along the walls of the container."

Encapsulated in a double-walled sleeve, this means uniform pressure around the circumference (at the hub) and along the shaft. The double-walled sleeve will expand and exert even surface pressure on the shaft and hub.
