OSSINING, NY — Metallized Carbon Corporation, a manufacture of oil-free, self-lubricating, carbon-graphite materials for severe service applications, announces the availability of bearings specially designed for dry running in high temperature applications.
The Metcar high temperature bearings are designed for use at temperatures ranging from 350 to 1000°F in oxidizing atmospheres, and from 350 to 6000°F in non-oxidizing atmospheres. At these high temperatures, oil-grease lubricated ball, roller, and sleeve bearings are problematic because the oil-grease lubricants can melt, volatilize or carbonize. Plastic and composite bearing materials can soften, deform or melt at such high temperatures.
Because Metcar carbon-graphite bearings rely on graphite for their self-lubricating properties, they are not subject to the shortcomings associated with petroleum-based lubricants at elevated temperatures. They are dimensionally stable, and are not subject to melting, softening, or deformation.
Metcar bearings are ideal for use in continuous dryers, high temperature conveyors, kiln cars, and high temperature ventilation dampers. They are also a great choice for other high temperature equipment, including continuous bakery ovens, screw conveyors, valves, and paint dryers.
