Product description
Norbert Grease WR 20 is an anhydrous calcium-based thickening grease based on a mixture of fully synthetic and polymer base oils. The grease contains antioxidants, anti-corrosive agents and extreme pressure/anti-wear additives.
The thickener combined with a special base oil mixture makes this product suitable for lubrication in heavy duty bearings and humid, corrosive environments. The grease has excellent adhesion and water resistance.
Norbert Grease WR 20 has been specially developed for marine applications and is suitable as a general purpose grease for use in forestry, agricultural and construction vehicles. It is also suitable for industrial applications where water washout and corrosion problems exist. Although the base oil viscosity of this grease is high, it can be easily pumped in most centralized lubrication systems. At low temperatures, Norbert Grease WR 0 is recommended.
Product features:
Super waterproof
Excellent corrosion resistance
Can withstand high impact loads
Excellent adhesion
Long life lubrication
