Medium Duty Industrial Gear Oil
Specialized for lubricating diverse gear transmission systems, gear oil constitutes a blend of either petroleum-based or synthetic lubricant oils, fortified with tailored additives including extreme pressure anti-wear agents and oily enhancers, designed to amplify its operational efficiency.
Product Details：Medium Duty Industrial Gear Oil
Gear oil is a kind of lubricant with excellent performance, which is mainly used for the lubrication of gear transmission mechanism such as transmission and rear axle. It not only plays the role of lubricating gears and bearings, preventing wear and rust, but also helps to dissipate heat from the gears, reduces tooth impact and noise, and has a washing function that removes contaminants and solid particles from the gear surface.

1. Advantages of Gear Oil
(1) Good lubrication performance: Gear oil is formulated with high quality base oil and additives, which can form a good lubrication film and significantly reduce the friction and wear between gears, thus prolonging the service life of gears.
(2) Excellent anti-wear performance: by adding anti-wear agents, extreme pressure agents and other special additives, gear oils can maintain the stability of the lubricating film at high temperatures and pressures, effectively reducing the wear of the gear surface. This is especially important for gears that are subject to high loads.
(3) Outstanding cooling performance: gear oil has good thermal conductivity, can quickly transmit the heat from the gear to radiate out, to maintain the temperature stability of the gear operation. At the same time, it can also absorb part of the heat generated by friction, preventing gears from being deformed due to high temperature.
2. Application Scenario
(1) Closed Gear Oil: Applied in closed gearboxes, it pays special attention to the requirements of extreme pressure anti-wear property, oxidation stability, etc.. It can be subdivided according to different load and temperature conditions, such as CKB antioxidant and antirust gear oil, CKC medium load industrial gear oil, CKD heavy load industrial gear oil and so on.
(2) Open gear oil: It is suitable for low-speed and heavy-duty gear units without gear box or with semi-closed gear box. It requires good adhesion and cohesion to ensure effective lubrication and protection of gears in an open environment. Open gear oils can also be subdivided according to load and temperature conditions, such as CKH ordinary open gear oil, CKJ extreme pressure open gear oil, CKM heavy duty open gear oil, etc.
