Abstract
The need is becoming more and more urgent for bearings operating at very high temperatures. But present-day liquid lubricants are temperature-limited owing to their characteristics, but graphite is chemically more stable and capable of being used as a lubricant. So in pursuit of information concerning the performances of the angular contact type ball bearing operating in an electric furnace under the graphite-air mist lubrication at high temperature, the frictional moment and temperature of bearing have been measured. The conclusion reached on the experimental results is as follows. The bearing can be run at surrounding temperatures up to 800°C without appreciable damage. The smaller the particles of graphite, the less frictional moments are obtained, but at very high temperatures the grading and consumption of graphite have little influence on the frictional moment. Small change in frictional moment occurs in accordance with variation of surrounding temperature. The moisture content of graphite has little influence on the frictional moment. The cooling effect of air is somewhat remarkable.
