Carbon-Graphite Bearings operate at high temperatures.

Press Release Summary:

FDA approved for use with food/pharmaceuticals, Metcar Bearings are designed for dry running at temperatures from 350–1,000°F in oxidizing atmospheres and 350–6,000°F in non-oxidizing atmospheres. Because bearings rely on graphite for self-lubricating properties, they are dimensionally stable and are not subject to melting, softening, or deformation. Typical applications include continuous dryers, high temperature conveyors, kiln cars, and high temperature ventilation dampers.

Metcar Bearings for Dry Running at High Temperature

Avoid problems experienced with oil/grease lubricated or plastic bearings in high temperature applications

Metallized Carbon Corporation, a global leader in the 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. Several Metcar Grades have received FDA approval for use in contact with foods and pharmaceuticals.

Metcar bearings for dry running can be provided to customer prints or custom-designed for specific application dimensions and tolerances. Standard pillow blocks and flange blocks with Metcar bearing inserts are available with cast iron, stamped steel, or stamped stainless steel housings. Metcar high temperature bearings are also available shrink-fitted into metal housings or metal retaining rings.
