How Gatke Compares to Alternative Materials

Materials Cost Difference Advantages Disadvantages
Babbitt +75 to 100% Old worn or misaligned equipment Lead-based, need for a casting, & machining – environmental concerns
UHMW – 50% Lower Price Can’t take more than 250 degrees F
Bronze + 0 to 25% Accepted technology – easy to machine – been around for a long period of time Three times heavier than Gatke – permanent deformation – environmental concerns
Steel – 25% Good heat resistance Very aggressive wear on shaft & galling
Other Phenolics +/- 10% More cost effective in smaller diameters – sizing in some instances Size 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
