Overview:
Heavy duty gear oil is an important lubricating oil with excellent performance that mainly composed on base oil or synthetic lubricants, made by adding extreme pressure anti-wear agents and oiliness agents, which is applied in a variety of gear transmission devices to prevent the wear, scoring and sintering of gear surface, extend the service life and improve the power transmission efficiency, with advantages of excellent wear resistance, suitable viscosity, good thermal oxidation stability, anti-foaming property, excellent oil-water separation performance and anti-rust performance and others.
Application:
Heavy duty gear oil is suitable for lubrication of driving shaft of automobile, engineering and mechanical drive axle and some gearbox gears, especially the vehicles equipped with hypoid gear and so on.
Feature:

• Sulfur-phosphorus compound additives with excellent wear resistance properties and carrying capacity can cope with a variety of harsh conditions, such as heavy vehicle climbing and emergency brakes.
• Outstanding heat resistance and anti-oxidation stability can effectively reduce the formation of oxides and keep the gear surface clean.
• Excellent pressure resistance and shock resistance can effectively prevent the erosion or peeling and other chemical reactions on the gear surface 
• Balanced formula makes the gear oil has good corrosion resistance and anti-rust performance.
• Excellent extreme pressure anti-wear property can effectively prevent abrasion and wear of the gear surface in high-speed impact and high torque and other harsh conditions.
• Excellent rust and corrosion resistance can effectively prevent rust and corrosion of the gear surface in damp conditions.
