Cast iron solutions

Metallized Carbon Corporation supplies standard, cast iron pillow blocks and flange blocks with self-lubricating, carbon-graphite bearing inserts for applications where oil/grease lubrication cannot be used. These bearing assemblies provide low friction and long, maintenance-free, wear life in very high temperature applications.

Applications include hot air dampers and butterfly valves for power plant boilers. These bearings are suitable for high temperature conveyors for drying, heat treating, baking, and annealing. They are also said to be excellent for ash drag out conveyors, kiln car wheel bearings and stoker bearings.

Rugged cast iron housings are used to hold steel encased, carbon-graphite bushings. Two bolt pillow blocks are available for shaft sizes to 3-1/2in diameter. Two bolt flange blocks are available for shafts up to 2-1/16 diameter. Four bolt flange blocks are available for shafts up to 5 inch diameter.

Three Metcar carbon-graphite grades are usually 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 to 750°F; and Metcar Grade 2500, high temperature electro-graphite, for temperatures to 1000°F.
