Product Description
Calcium Sulfonate Complex Extreme-Pressure Grease. KATMOTO GREASE CSC EP2 is a premium calcium-sulfonate complex extreme-pressure grease offering inherent high EP performance, outstanding water and corrosion resistance and very high dropping point for the most demanding wet, high-temperature and shock-loaded mining and construction applications
Key Performance Features
| Inherent extreme pressure
calcium-sulfonate complex provides very high EP without sacrificing corrosion control. |
Outstanding water resistance
excellent water washout and spray-off resistance for wet mining conditions. |
| Very high dropping point
supports high-temperature operation in severe-duty applications. |
Superior corrosion protection
protects bearings against rust and corrosion in harsh environments. |
| Mechanical stability
resists softening and leakage under heavy load and vibration. |
Severe-duty mining grease
ideal for extreme-pressure, wet and high-temperature mining duty. |
Applications & Performance Level
| Applications | Severe-duty bearings, pins and joints in wet, high-temperature and extreme-pressure mining and construction applications requiring an NLGI 2 calcium-sulfonate complex EP grease. |
| Specification | NLGI 2 (Ca sulfonate complex) — high-EP, water-resistant grease classification. DIN 51502 KP2P-20 — high-performance EP grease designation. Water & corrosion resistant — excellent washout resistance and rust protection. High 4-ball weld — very high load-carrying for severe-duty joints. High-temperature capable — very high dropping point for hot operation. |
| OEM Suitability | Severe-duty wet and high-temperature mining and construction bearings and joints specifying an NLGI 2 calcium-sulfonate complex EP grease. Follow the OEM manual. |
| Important Notice | Use only where the equipment manufacturer specifies this grade/type and a matching performance level. ”Suitable for” does not mean official approval unless separately certified. Always follow the OEM manual. |
