CALCIUM SULFONATE COMPLEX GREASE IN ELECTRIC MOTOR BEARINGS
This paper seeks to examine the key parameters affecting the performance of a new electric motor bearing CSC grease. The effect of thickener content, base oil type/viscosity, and additives on the performance of the finished grease is evaluated. Regardless of the thickener type or base oil chosen, the ideal grease in an electric motor bearing application must withstand high speeds and temperatures for extended periods. Typical additives for such greases impart antioxidant, anti-wear and anti-corrosion properties. By choosing a CSC grease, many performance requirements are inherently fulfilled. Although typical CSC thickener contents may prove too high for many motor bearing applications, this study examines a new process of grease manufacture which results in an overall lower thickener content of the final product. The samples generated are evaluated for oxidation resistance, anti-wear properties and thermal- and mechanical stability. The rheological properties are also investigated.
