Silicon Carbide Seals and Bearings Applications

Silicon carbide is ideal for extreme environments, due to its exceptional wear and chemical resistance, enhanced dry running capability and high hardness.

The robust properties of our silicon carbide materials make them the ideal choice for use as mechanical components and wear parts that are specified in applications such as:

  • Centrifugal pumps
  • Submersible pumps
  • Compressors
  • Mixers and steam joints
  • Gear pumps
  • Propulsion shaft sealing
  • High temperature and pressure applications
  • Abrasive and aggressive fluid applications
  • Mechanical seals for circulating pumps with limited dry running capability
  • Bearings for circulating pumps
  • Specialty pumps for handling corrosive and abrasive fluids
  • Bearings for electric water pumps used in electric and/or hybrid cars

Our market leading PGS graphite loaded sintered materials are the preferred choice for many of the respected mechanical seal manufacturers who demand the best possible tribological performance in hard on hard seal face and bearing combinations. While our proprietary SiC grades (PGS3 and PS5000) offer unique chemical compositions that are tailored to customers specific requirements. Our SiC products are also Water Regulations Advisory Scheme (WRAS) approved for being in contact with drinking water.

We work closely with our customers to understand the operating parameters of the application and the range of process conditions to manufacture precision SiC components in high volume with sizes up to 80mm in diameter. This evaluation determines the design of the end product and provides the selection criteria to offer the best material and the most cost effective solution for the specific needs of the customer’s design.
