Circoolmatic Extends Stern Tube Seal Life A major marine problem has been the fric-tional heat developed in the forward stern-tube seal, which causes the forward rubber seal rings to become brittle and subject to crack-ing. Waukesha Bearings states that they have introduced a totaly new seal oil-lube cooling system that substantially reduces this problem to increase seal life. By means of this cooling system, descrip-tively named Circoolmatic, hot oil is pumped from the forward seal into an oil reservoir fitted with a seawater cooling coil. Constant circulation of the oil through the cooling sys-tem assures maximum lubrication, dissipating the frictional heat and reducing forward-seal deterioration. A panel with pilot lights, audi-ble alarm, and low-level switch is provided for controls and monitoring. The entire system, weighing less than 140 pounds, is packaged into a compact unit for easy "installation by ship or shipyard tech-nicians, on new or retrofitted ships. It is rec-ommended that the system be employed on all seals measuring 710 mm or larger and/or on ships carrying hot cargo in the aft tanks, inducing heat into the shafting and seal. Circoolmatic is available for prompt deliv-ery, completely assembled and ready for in-stallation. Complete price per unit is $750, from Waukesha Bearings Corporation, P.O. Box 798, Waukesha, Wis. 53186. Ocean Science Appointed West Coast Representative For Oceans International David D.
