Cast iron pillow blocks and flange blocks with self-lubricating, carbon-graphite bearing inserts can be used for applications where oil/grease lubrication cannot. These bearing assemblies provide low friction and long maintenance-free wear life in high-temperature applications. They are ideal for high-temperature conveyors for annealing and heat treating. Three carbon-graphite grades are supplied: Metcar Grade M-11, carbon graphite, for light loads at temperatures up to 700°F; Metcar Grade 1515, copper-impregnated carbon graphite, for higher loads at temperatures up to 750°F; and Metcar Grade 2500, high-temperature electro-graphite, for temperatures up to 1000°F.
