Carbon Stoker Bush
Carbon Stoker Bushes are typically made from high-quality graphite or carbon -graphite composites. Carbon-graphite stoker bushes are used in travel grate of boilers for high temperature applications because metal bushes need oil/grease lubrication, lubricants can start to melt, volatilize or carbonize above this temperature above about 350ºF (177ºC).
These solid homogeneous materials do not contain oil/grease lubricants and they do not rely on oil/grease for lubrication. Thus, bearings manufactured from these carbon graphite materials are not subject to the shortcomings associated with petroleum-based lubricants and metals at elevated temperatures.
