ETP-H Model
A hydraulic pump forces oil into the sleeve, moving the wedge of the built-in tapered piston, thereby firmly joining the shaft and hub via the sleeve. Since the shaft and hub are held in place solely by the wedge effect of the tapered piston, this design features a very high torque capacity and is capable of withstanding heavy thrust loads.
