SILICON CARBIDE SLIDING BEARINGS

EKasic® SILICON CARBIDE (SiC) SLIDING BEARINGS

Applications

EKasic® silicon carbide sliding bearings have a proven track record in pumps plant and process engineering. For example in:

  • Hermetically sealed pumps (e.g. centrifugal and gear pumps)
  • Stirrers

Properties

Thanks to the specific properties of sintered silicon carbide materials, the EKasic® bearings can even operate in waters, acids and strong alkalis. The high hardness crushes foreign particles in the process fluid. If there is a risk of dry running, the bearings can also be coated, e.g. with DLC (=diamond-like carbon) coatings.

EKasic® silicon carbide materials also offer outstanding specific properties for use in sliding bearings:

  • EKasic® F
    the standard material with high hardness and good corrosion resistance
  • EKasic® C
    the most corrosion-resistant material with high hardness and good tribological properties
  • EKasic® G
    the material with improved load-bearing characteristics and suitability for short-term dry running  

Customized solution or standard

We produce these sliding bearings exclusively to customers’ specifications. An extremely wide variety of forms and geometries can be implemented.

In addition, we offer the modular EKasic® standard sliding bearing system based on the EKasic® family of materials, which have proven their reliability in millions of bearings. It provides a series of carefully matched, ready-to-install components.
