A new series of Graphalloy self-lubricating bushings mounted in stainless steel flange blocks is now available from Graphite Metallizing Corp. The new series combines the corrosion resistant and self-lubricating properties of Graphalloy with the application and installation versatility of a flange block. Graphalloy stainless steel flange blocks are available in 2-bolt and 4-bolt configurations, come in a wide range of base dimensions, and can accommodate shaft diameters from 0.5 in. (12.7 mm) to 3.75 in. (92.5 mm). Graphalloy is suitable for temperatures of 750°F and above in non-oxidizing environments or with oxidation-resistant grades. According to the company, the flange blocks deliver lifetime cost and operating advantages for equipment in hard-to-lubricate environments. Graphalloy, a graphite/metal alloy, is graphite impregnated with metal to enhance the chemical, mechanical and tribological properties of the material. The material, most commonly used in bushings, is available in more than 100 grades and can be designed to fit a variety of machinery. www.graphalloy.com
