Graphalloy bearings are designed to perform where others fail — even in the harsh, cold, and corrosive conditions of seafood processing. From cryogenic lines to constant washdowns, they deliver lasting performance with zero maintenance.

Graphalloy® Custom Babbitt-grade Bushings and Thrust Washers for North Sea Application

Pump company was designing and manufacturing a small end suction pump which uses a magnetic drive. They needed radial and axial bearings for the pump, which would be installed in a harsh environment – an oil & gas company’s off-shore platform in the North Sea.

Graphalloy® “Can” Do It!

 In early January, a leading aluminum beer-can producer approached Graphalloy to upgrade the roller bearings in their heat-treating ovens. After installing our self-lubricating pillow block assemblies, they’ve enjoyed eight weeks of maintenance-free, grease-free operation with zero failures or contamination. Impressed by the results, they’ve requested a quote for 26 additional units to roll out the solution across their production line.

Bearings for Extreme High Temperatures

Many bearing materials claim to be high temperature performers, but on closer inspection, they can't perform in the temperatures required for ovens, furnaces, and more. But Graphite-metal alloys are true high temperature performers, with the ability to reach temperatures of 750°F (400°C) and higher. This material is used in steel mills, food ovens, heat treat furnaces, molten sulfur pumps, roasters, and more, due to its ability to handle extreme heat and stay self-lubricating. Learn more about how graphite-metal alloys can help your high temperature bearing application.

Graphite for Seals

GRAPHITAR® carbon is an ideal material for use as a sliding face within a mechanical seal configuration, operating successfully against counterfaces in materials such as Silicon Carbide , Tungsten Carbide and other ceramics. GRAPHITAR is a very hard material and extremely resistant to wear. It is lubricated by most fluids so that the medium being sealed can serve as the seal lubricant. GRAPHITAR’s permeability can be controlled to allow the lubricating medium to be metered to the sealing surface or to be impervious and fully “Leak Tight” to 6 BAR pressure of nitrogen.

Submerged Bearings

Many tough applications run completely underwater, partially submerged, or with washdowns. Often in these applications, caustics are also an issue. Therefore, it is important to have a bearing material that is dimensionally stable, can handle caustics, and can provide lubrication in various environments. Graphite-metal alloy bearings can be a solution here. Learn more about submerged bearings here.

Nickel-Impregnated Graphite Bushings

Nickel-impregnated graphite bushings can handle temperatures of up to 750°F/400°C in oxidizing environments and 1700°F/725°C in non-oxidizing/submerged environments, as well as handle low lubricity service and run-dry scenarios. This makes them a good match for pumps in tough services. Learn more here.
