Metallized Carbon Corporation offers machinable, resin impregnated, carbon-graphite blanks for companies that need to machine mechanical seal primary rings, radial bearings, thrust bearing, case wear rings, or pump vanes on an emergency basis.
The machinable blanks are made from fine-grained, high strength, molded carbon-graphite that is fully impregnated with chemically resistant, thermal setting resin. The material has excellent lubricating qualities when running in low viscosity liquids in the temperature range between -400˚F and over 500˚F. The blanks are readily machinable with conventional tungsten carbide or diamond tools. Mechanical seal rings, bearings, and vanes machined from these blanks are impervious to high-pressure liquids. The material is dimensionally stable so that mechanical seal ring faces can be polished to one Helium light band flatness, and the flatness is retained indefinitely. The material is chemically resistant to almost all liquids except extremely strong, oxidizing acids and alkalis.
Forty-nine standard cylinder sizes are available to cover mechanical seal ring and bearing sizes up to10-15/16 inch outside diameter by 3-1/8 inches long. Blocks 4-5/8 inch wide by 8 inch long by up to 2 inches thick are also available.
Two different Metcar, machinable, blank grades are kept is stock to cover a wide range of applications. Those grades include Metcar® Grade M-400, for general duty applications (CS Series Blanks), and Metcar® Grade M-106, for high load, high speed applications (HS Series Blanks).
