Koppers has expanded from their full line of shaft couplings, with a licensing arrangement for the Maag Synchronizing Clutch. Utilizing the double engagement gear coupling prin-ciple for torque transmission, this unit features a hydraulically-controlled synchronizing mechanism. It engages or disengages on defi-nite command only. With this move, Koppers can now be of even greater service in helping you transmit power efficiently and profitably.
