The environment in a rubber curing autoclave is 300ºF (150ºC) and has live high pressure steam. The grease-lubricated roller bearings were failing due to high heat and moisture, causing interruptions in production. When a bearing failed, production was stopped due to the short shelf life of uncured rubber. GRAPHALLOY® bushings were installed and, after more than one year, there has been no production interruptions. If replacement is necessary, it can be done during scheduled outages because self-lubricating GRAPHALLOY will not seize the shaft.
