DuPont Krytox PFPE Greases from Fluid Seals and Packings can outperform regular synthetic and petroleum greases in the toughest of conditions. A case study was performed on Rod Mill. Cost savings were realised from this case study, downtime and environmental impact was also reduced. The findings of this case study concluded that:

  • Roll bearing temperatures exceed 204°C (400°F)
  • Semi-molten copper, 950°C (1750°F), is shaped using rollers cooled by oil/water emulsion
  • Bearings, rollers and shafts had to be replaced every month
  • PFPE grease was tested and only 4 bearings were replaced where formerly 180 had been replaced
  • Greased with synthetic grease every 4 hours
