Carbon Graphites

For dynamic seals, sliding bearings and hot glass contact

Carbon Graphite

With Schunk at your side, you can rely on "high-performance materials" - also for carbon graphite. Our international customers benefit not only from our high-quality solutions, but also from our application technology consulting and our product diversity. In the Mechanical Carbon sector, Schunk carbon graphite materials are often used as a reference.

What distinguishes our carbon graphite?

We speak of carbon graphites when the bodies are temperature treated at a temperature below 1200°C, i.e. carbonized. After carbonization, there is still no continuous graphite structure; the bodies are of high strength and hardness.  For many applications, however, such carbon materials already have the desired properties. These include, for example, high wear resistance, excellent sliding properties, high dimensional stability even under temperature, and an ideal surface finish for the desired application in  question. We achieve our material and product diversity through various manufacturing, processing and finishing techniques - we have the right material for every requirement.

Where is our carbon graphite used?

The main area of application for our carbon graphite is in the field of seals - for example, for slide bearings, dynamic seals and shaft seals. Our customers also rely on the exceptional properties of carbon for the manufacture and transport of glass products, e.g. as support blocks or transport pins.

In the segment of electrical motors for household-equipment, like washing machines or vaccum cleaners, Schunk is world market leader with the most modern and most reliable caron brush grades for such application. Extended brush lifetime and excellent radio interference performance are 2 of the main USPs.

  • High wear resistance
  • Very good sliding properties / lubricating properties
  • Tribological properties
  • Dimensional stability even under temperature
  • Individually adjustable surface properties
  • Chemical resistance and therefore no adhesion to glass products
