Heavy Duty Circulating Gear Oil

Heavy Duty Circulating Gear Oil is a heavy-duty gear oil designed specifically for industrial centralized circulating lubrication systems. It is suitable for enclosed gearboxes that operate continuously for extended periods, providing stable oil film protection under high load and high temperature conditions.

Extreme Pressure Anti-Wear Protection: Extreme pressure additives form a protective film under high loads, reducing the risk of metal-to-metal contact. FZG testing achieves ≥12 grade (A/8.3/90), effectively reducing pitting and wear on gear surfaces.

High-Temperature Oil Film Stability: High viscosity index base oils maintain a stable oil film under high-temperature shear conditions, preventing lubrication failure and making them suitable for equipment operating at continuous high temperatures.

Anti-oxidation Extended Life: The anti-oxidation system inhibits oil degradation and sludge formation, extending oil change intervals to 6–24 months (depending on operating conditions).

Anti-foaming and Air Release: Rapid defoaming and air release design reduces bubble retention, preventing oil film breakage and pump cavitation, and improving circulation system stability.

Anti-emulsification and Water Separation Capability: The rapid oil-water separation structure quickly restores lubrication performance in humid or water-ingress conditions, reducing the risk of emulsification.

Steel Industry: Used in rolling mill and reducer gear systems, adaptable to high-impact and high-load continuous operation.

Cement Industry: Used in rotary kiln and ball mill reduction gears, adaptable to high-temperature and dusty environments.

Mining Machinery: Used in crusher and conveyor system gearboxes, bearing heavy loads and impact conditions.

Power Systems: Used in power generation equipment gear transmission systems, supporting long-term stable operation.

Ports and Shipbuilding: Used in lifting and transmission equipment, maintaining stable lubrication in high-humidity environments.

International Standards: Complies with DIN 51517-3 (CLP) and ISO 12925-1 (CKD), suitable for industrial enclosed gear systems.

Material Compatibility: Compatible with common sealing materials such as NBR and FKM, reducing the risk of leakage.

OEM Equipment Compatibility: Suitable for industrial gear systems such as Siemens Flender and SEW (meets CLP lubrication requirements).

Raw Material System: PAO / Hydrogenated Base Oil / Highly Refined Mineral Oil.

Additive System: Extreme Pressure Anti-wear + Anti-oxidation Composite System, ensuring batch stability.

Production Management: Compliant with ISO 9001 / ISO 14001 standards.
