How Gatke Compares to Alternative Materials

MaterialsCost DifferenceAdvantagesDisadvantages
Babbitt+75 to 100%Old worn or misaligned equipmentLead-based, need for a casting, & machining – environmental concerns
UHMW– 50%Lower PriceCan’t take more than 250 degrees F
Bronze+ 0 to 25%Accepted technology – easy to machine – been around for a long period of timeThree times heavier than Gatke – permanent deformation – environmental concerns
Steel– 25%Good heat resistanceVery aggressive wear on shaft & galling
Other Phenolics+/- 10%More cost effective in smaller diameters – sizing in some instancesSize limitations – we can produce larger diameter

Kor-Pak Can Solve Problems Where:

  • Chemical solutions destroy metal bearings
  • Grit and Dust Destroy Metal Bearings
  • Bronze doesn’t work or Thermoplastics fail
  •   Maintenance Problems
  •   Environment Hazard
  •   Lubrication–availability of lubrication & temperature are problematic
  • Custom product design is needed
