Metallized Carbon (Metcar), a manufacturer of oil-free, self-lubricating, carbon-graphite materials for severe-service lubrication applications, has announced its carbon-graphite bushings are available for use in gear pumps that pump aviation fuel for aircraft engines. The carbon-graphite bushings, which are used to support both the drive gear shaft and the idler gear shaft, are preferred for that application because they can use aviation fuel as the bushing lubricant. Aviation fuel is a low-viscosity liquid that produces only an extremely thin hydrodynamic film, too thin to provide adequate lubrication for traditional metallic bushings.
