Product Introduction
Features
Excellent property of EP AW (Extreme Pressure, Anti-wear), water resistance, adhesion, mechanical invariability and High Temperature Performance. And good protection performance to metal.
Application
Applicable between -20℃ to +180℃, 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.
