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.
