St. Marys Carbon

St. Marys Carbon makes parts from carbon graphite, electro graphite, resin bonded graphite and metal graphite. The company has been in business since 1939. Its phone number on the site is 814 781 7333.

The company says it is one of the few carbon makers in the world that develop their own carbon grades. It says it makes its products in house. A product development team designs custom parts, and account managers follow each order.

The product list is long. It includes brushes, Silver Dot dryer bearings, ARC electrical contacts, bearings and bushings, mechanical seal rings, hot glass handling parts, rotors and vanes, Halo series turbine and compressor rings, wear plates and graphite plugs, and carbon material blanks.

The site groups its work by use. These include electrical transmission, dry running and self lubricating parts, high and low temperatures, corrosive settings, high friction, sanitary settings, marine settings and high altitude. Aviation is one of many fields the company serves, and the turbine and compressor rings are the products most linked to engines.

The site lists two quality certifications, AS9100:2016 and ISO 9001:2016. It offers product data sheets, catalogs, brush grade guides, safety data sheets and terms of sale for download. Blog posts cover seal types, why bearings fail and carbon graphite conductivity. The company also has a careers page and a form to contact its material and application specialists.
