Metal face seals

HDDF metal face seal
SKF metal face seals type HDDF (fig 1) are designed for use under severe service conditions at relatively low circumferential speeds. They offer reliable protection against solid and liquid contaminants as well as leak-proof retention of lubricants. The seals were originally developed for off-road and tracked vehicles, but have been found to be equally suitable for a range of other applications where effective protection is required against sand, soil, mud, water etc. (fig 2). These applications include:
  • all types of mixers
  • sand treatment equipment
  • conveyors and other construction equipment
  • agricultural machinery
  • washing equipment
  • grinding mills and other pulverizing equipment
  • ore dressing equipment
  • mining equipment
