High Temp GRAPHALLOY® Bushings Handle Hot, Harsh Environments

Self-lubricating GRAPHALLOY® bearings operate in high temperatures up to 750°F (400°C) in air and up to 1000°F (535°C) in non-oxidizing atmospheres. GRAPHALLOY, a graphite/metal alloy is uniform throughout and contains no oil or grease to harden or burn up in high temperatures or under load. Since they do not soften, gum, or seize in hot and harsh applications, as grease-lubricated and plastic bearings may, GRAPHALLOY bearings/bushings reduce maintenance, eliminate need for frequent replacements, and provide trouble-free operation.

Available in over 100 grades with specific properties to suit a wide range of operating conditions, GRAPHALLOY can be used in water, hydrocarbons, weak acids, and alkalies, and works submerged. Commonly used materials are copper, bronze, silver, and nickel.

GRAPHALLOY products include bushings, flange bearings, hanger bearings, pillow blocks, seals, case rings, thrust washers, wheel assemblies, and electrical contacts, and are available in custom designs or as standard components. Typical applications include ovens, furnaces, conveyors, dryers, dampers, pumps, and plating tanks. GRAPHALLOY has received FDA acceptance and can be steam cleaned without damage or performance reduction.
