Cercar L-CKD Heavy-Duty Industrial Gear Oil
Product Description
Cercar L-CKD Heavy-Duty Industrial Gear Oil
Key Features
- Exceptional extreme-pressure anti-wear properties effectively prevent gear surface scuffing, wear, and scoring, ensuring stable operation under heavy loads and significantly extending gear service life.
- Excellent oxidation and thermal stability maintain consistent performance during prolonged use in high-temperature environments, extending oil change intervals and reducing operational costs.
- Superior rust prevention and demulsibility protect critical components from corrosion in case of water ingress during operation.
- Outstanding foam resistance provides stable oil film protection for effective lubrication and heat dissipation, ensuring optimal equipment performance.

Performance Benchmarks
Applications
- High-load enclosed gear drives in mining industry (large mining excavators, mine hoists)
- Gear transmission systems in cement industry equipment (large grinding mills, rotary kilns)
- Low/medium-speed large enclosed gear drives with contact stress below 1100MPa(N/mm²) in fertilizer and metallurgical industries (blast furnace hoists, rolling mill gearboxes)
Usage Guidelines
- Storage: Maintain between -10°C to 40°C in indoor/sheltered areas protected from sunlight and moisture to prevent container rusting.
- Change Interval: 6,000-10,000 operating hours or 1-1.5 years (adjust based on oil analysis).
- System Cleanliness: Achieve minimum ISO 17/15 cleanliness before oil changes by removing all contaminants.
- Seal Compatibility: Compatible with NBR, FKM and other common sealing materials.
- Precautions: Use dedicated containers. Strictly prevent water ingress, contamination, and mixing with other oil types during storage/transport.
