Hub-Shaft connection for quick and accurate mounting

ETP-EXPRESS functions as a hydraulic connection, operating with a single screw for pressurizing. The result? Quick mounting, dismantling, as well as hub repositioning and adjustments, that can all be easily performed with impeccable accuracy.

Quick mounting and compact design

Construction: ETP-EXPRESS consists of a double-walled, hardened steel sleeve, filled with a pressure medium, and a flange part containing a pressure screw and piston with seals to maintain pressure.

Operation: When the pressure screw is tightened, the sleeve expands uniformly against the hub and shaft and creates a rigid joint. Dismantling is done simply by loosening the screw. ETP-EXPRESS then returns to its original dimensions and can be easily dismantled.

Allows precise synchronization with additional machine elements quickly and easily.
