Advance Carbon Products was founded in 1956, as Advance Carbon & Electric Mfg. (ACEM), with the original facility located in a small shop in San Francisco. After successfully producing carbon brushes and mechanical graphite products for several markets, ACEM was reorganized into two different companies in 1962, one being Advance Carbon Products, Inc. (ACP) In 1966 Advance Carbon Products was purchased from the parent company by the management team which included one of its original founders, William J. Crader, Jr.

ACP is one of the few carbon manufacturing companies producing a complete line of carbon products. We have machine shop facilities to manufacture carbon brushes as small as .060" square, to segmented seal rings as large as 12 ft in diameter. Among many other items, our shop equipment consists of conventional and CNC lathes and mills, grinders, lappers, and diamond saws.
