Flange Block/Pillow Block AssembliesCast iron pillow blocks and flange blocks with
self-lubricating, carbon-graphite bearing inserts for applications where
oil/grease lubrication cannot be used are available. These bearing assemblies
provide low friction and long, maintenance-free, wear life in high-temperature
applications where oil/grease lubricants would melt, volatilize or carbonize.
These bearings are ideal for high-temperature conveyors for drying, heat
treating and annealing. Rugged cast iron housings are used to hold
steel-encased, carbon-graphite bushings. Three Metcar carbon-graphite grades
are usually supplied: the Metcar Grade M-11, carbon-graphite, for light loads
at temperatures up to 700°F; the Metcar Grade 1515, copper-impregnated
carbon-graphite, for higher loads at temperatures up to 750°F; and the Metcar
Grade 2500, high-temperature electro-graphite, for temperatures up to 1000°F.
