Description
Sinopec LC Mining Grease is a high extreme pressure lubricating grease, formulated with high viscosity mineral base oil (> 400 cSt at 40°C) and a lithium complex thickener. It is available in NLGI grades 1 and 2. The grease contains antioxidants, EP additives, and solid lubricating additive Molybdenum disulfide (MoS2 or ‘moly’), providing protection for equipment operating under harsh conditions and vibratory loads in various applications such as mining equipment (rock crushers), wood pellet mills, and feed pellet mills.
Applications:
Sinopec LC Mining Grease is suitable for use in:
- Lubrication of off-road mining equipment, especially for slow-speed rolling bearings and plain bearings (bushings) under very high load, shock load, and vibration conditions.
- Heavy construction equipment, earth-moving machinery, mobile and stationary equipment.
- Heavy-duty applications in hard-to-reach locations requiring extended lubrication intervals.
Features and Benefits:
- Excellent Anti-Wear and Extreme Pressure Properties: Protect bearings from wear under heavy and shock load conditions, extending equipment life.
- Solid Lubricating Additive with Molybdenum Disulfide (MoS2): Enhances load-carrying capacity and protects metal surfaces from wear in conditions where vibratory shock loads can expel grease from metal surfaces.
- Lithium Complex Thickener: Ensures high dropping point, which means higher operating temperature range (-10°C to +150°C), and provides excellent mechanical stability, preventing grease breakdown.
- High Viscosity Base Oil: Maintains good oil film thickness under high temperature conditions, protecting components from wear.
- Excellent Water Resistance: Ensures the grease remains in place and is not washed or sprayed off in wet conditions, reducing grease wastage.
- Excellent Rust and Corrosion Protection: Extends component life and maintenance intervals.
- Good Thermal and Oxidation Stability: Ensures longer grease life under high temperature conditions, providing optimal lubrication, extending equipment life, and reducing maintenance requirements.
- Available in NLGI Grades 1 and 2: NLGI 1 grade can be used in central lubrication systems where pumpability is required.
