Graphalloy® introduces 327 lower profile pillow blocks


Graphite Metallizing Corporation, the manufacturers of self-lubricating Graphalloy® bushing materials for high temperature, low temperature, submerged, food, and other tough applications adds a new lower profile 327 pillow block.

The 327 pillow blocks are Graphalloy self-lubricating bushings mounted in stainless steel pillow blocks. This series combines the corrosion-resistant and self-lubricating properties of Graphalloy with the application and installation versatility of pillow blocks. These pillow block assemblies are self-aligning and can withstand temperatures up to 1,000°F.

The new lower profile 327 pillow block has a center line height of 1 3/32” versus the original profile center line height of 1 11/32”. With both pillow blocks in the Graphalloy catalog, there are now more opportunities to solve tough bearing problems for a variety of equipment. Graphalloy stainless steel pillow blocks work exceptionally well when submerged in water, water-soluble chemicals, and other corrosive or hostile liquids such as acids, alkalies, hydrocarbons, black liquor, and liquid gases. In these environments, plastic bearings may fail because of their tendency to soften or swell when submerged.

These pillow blocks are available in industry standard two-bolt configurations, come in a range of base dimensions, and can accommodate shaft diameters from 0.5” (12.7 mm) to 1.5” (38.1 mm).

Graphalloy, a graphite/metal alloy, is formed from molten metal, graphite, and carbon. It is a uniform, solid, self-lubricating bushing and bearing material that offers superior performance in hundreds of applications. Graphalloy is well-suited for submerged or high temperature applications where grease, oil, and plastics fail.
