Properties:

  • Excellent high temperature resistance;
  • Excellent extreme pressure anti-wear (EPAW) and heavy load capability;
  • Outstanding water resistance, adhesion, mechanical invariablity ;
  • Good protection performance to metal.

Application area:

  • Recommend for lubrication of bearing under such severe conditions like high temperature, high-humidity, water spray, heavy load and impact load etc. For example, lubrication of roll bearing of cold-rolled and hot-rolled of metallurgical equipment, and charging roller table bearing of steel mill.;
