Keeping Your Thrust and Guide Bearings Cool

Hydro electric generators have thrust and guide bearings usually working in an oil bath. Coolers with extended “spiral” fins are installed in the oil bath to remove the heat generated by friction in the bearings. Unifin coolers have extremely long life and typically only need replacing after a period of 30 year or more. They are not typically cleanable or repairable and are replaced when they are no longer functional.
