Carbon Bearing

  • Plain bush / bearings for electric water pumps.
  • Low friction and long life brought by unique carbon material and tribology technologies.


EKK manufactures carbon materials for bush / bearings by blending carbon graphite with resin and hot molding by a heat press followed by heat treatment at a prescribed high temperature.

The sliding carbon material for water pump mechanical seals, well-proven in use with coolant, is used to offer superior heat, wear resistance comparing to plastic plain bearings in the market.
