THE HOT BOX PROBLEM IN ITS RELATION TO BEARING METALS

The relationship between overheated journals in "hot boxes" is discussed as related to metals used as bearing metals. Although overheating is caused by the loss of oil film between the bearing and journal, the reasons for some bearings to overheat are not known. This article discusses the need to either determine new metals for bearings or reduce the temperature of journals to avoid the problem.
