Graphite-and-alloy bushings and bearings

April 20, 2000
Bushings and bearings made of Graphalloy, a graphite-and-metal alloy, work in hostile environments and handle temperatures ranging from cryogenic to 1,000°F.

Bushings and bearings made of Graphalloy, a graphite-and-metal alloy, work in hostile environments and handle temperatures ranging from cryogenic to 1,000°F. Graphalloy from Graphite Metallizing Corp., Yonkers, N.Y., does not melt or cold flow, provides a low coefficient of friction, and resists galling when run with close tolerances against rotating metal elements. The material also maintains dimensional stability under load, when submerged, and at high temperatures. It is corrosion resistant in most liquids including sulfuric acids and caustics. The self-lubricating bushings and bearings work in pumps, mixers, ovens, furnaces, dryers, and dampers.
