A series of Graphalloy self-lubricating bushings mounted in stainless-steel flange blocks is now available from Graphite Metallizing Corporation.
The 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 two-bolt and four-bolt configurations, come in a wide range of base dimensions and can accommodate shaft diameters from 0.5in (12.7mm) to 3.75in (92.5mm).
Graphalloy is suitable for temperatures of 750F and above in non-oxidising environments or with oxidation-resistant grades.
Graphalloy stainless-steel flange blocks are claimed to provide reliability and years of trouble-free operation.
These flange blocks can be used in high-temperature ovens, low-speed and stationary applications such as dampers, and other hard to lubricate environments - all places where other bushings will not work.
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.
