bearing considerations for high-temperature applications
Bearings for Dry Running High Low Temp Applications
Carbon/graphite bearings and thrust washers are used in high-temperature applications because oil/grease lubrication begins to volatilize or carbonize above approximately 350F (177C) When this occurs metallic bearings start to experience high friction high wear galling vibration and even seizing
