Kyodo Yushi Powerlite WR Grease
Product Made in Japan
Manufacturer : Kyodo Yushi
Model: Powerlite WR
POWERLITE WR is a next generation environment-responsive grease designed for applications under harsh conditions where water resistance and load carrying capacity are imperative.
It uses purified mineral oil as its base oil and calcium sulfonate complex as its thickener. Containing no heavy metal like molybdenum, the next generation eco-friendly grease is superior in water resistance, rust prevention, load carrying capacity and shear stability.
Characteristics of Powerlite WR
- 1.Water resistance
- Its prominent adhesion brings resistance to washing, offering exceptional water resistance.
- 2.Rust prevention
- Calcium sulfonate complex, the thickener of the grease, is widely used for anti-corrosion detergent for engine oils, providing excellent sustainable rust prevention.
- 3.Load carrying capacity
- As the thickener ingredient serves as solid lubricant, having wear resistance and EP lubricity higher two-times or more than those of molybdenum disulfide.
- 4.Shear stability
- Owing to the thickener contained plentifully, the grease changes little in consistency even in moisture state, resisting to softening and leakage derived from mechanical shear.
- 5.Environmental friendliness
- It is eco-friendly, easier to be disposed of and not contaminate cooling water as the grease contains no heavy metal and sinks under water.
Main Applications and Applicable Components
- Work roll bearings of mills at ironworks
- Bearings of machinery equipment at paper mills
- Industrial machinery (agricultural machines, construction machines, etc.)
- Facilities for dams, hydropower generation and flood control, etc.
