bearing hydraulic nut

The hydraulic nut is a design base on the Pascal's law , using a hydraulic pump to inject the oil into the chamber of a nut to push the piston out which generate a huge force to drive-up a conical component on its taper seating to get the tight fit. It is widely using inmounting and dismounting bearings, gears and couplings with taper bores.
