Mechanical Shaft Seal Face

Mechanical seals are mainly used for high speed sealing between liquids and two gases the two surface aids the lubrication of the two surface, conduct heat caused by friction and improve the sealing effect. The diameter of the counter face should be the same or larger than that of the carbon ring. the finish of the carbon wearing surface and of the counter face is critical to the relative wear rate. Counter face : Grey cast iron, plain, steel alloyed steel hard
metal, ceramic, glass, tungsten carbide, silicon carbide.
