Graphalloy bearings in pillow block and flange block housings are a maintenance-free solution for wastewater treatment plants. Graphalloy bearings are self-lubricating, non-galling and dimensionally stable, meaning they can operate for years in tough wastewater applications.

Graphalloy is a graphite-metal alloy. As such, it will not swell when submerged or lose lubrication like other bearing materials. Graphalloy bearings are both reliable and low friction.

Available in standard size pillow blocks and flange blocks, the bearings are easily installed in such wastewater applications as flocculators, clarifiers, aerators and more.  

Long service life

In one example, Graphalloy bearings in pillow blocks were installed in the rotating biological contactor systems at a wastewater treatment plant. The bearings were on either end of each shaft, and one system was always running. Over 20 years later, the bearings were pulled and replaced with new Graphalloy bearings. However, the original bearings were found to be still functional, after all those years of tough service.

The Graphite Metallizing Corp., makers of the Graphalloy bearing material, was founded in 1913 in Yonkers, New York. Over the years, the company continually innovated around the product to create more products and grades, including FDA-acceptable grades and NSF-certified grades.
