They’re also beneficial in high-pressure situations. They are manufactured in a wide range of viscosities, with ISO grades 32 to 6800 available. Whether the temperatures are extremely low or extremely high, synthetic gear oils are the best choice when other oils simply will not function. These oils, made from poly alpha olefin and additives are primarily used for extreme machine conditions. Synthetic gear oils are more of a niche product than synthetic motor oil, which is highly desirable. These are mainly compound gear oils & frequently used in high-pressure industrial or automotive gear applications. When combined with the appropriate additives, the result is an oil that is suitable for low-speed, high-pressure applications while maintaining high lubricity. The viscosity of a gear oil can be increased significantly by combining it with fatty oils. Other anti-wear additives, such as zinc-based protectants are desirable for applications containing metals that are easily affected by chlorine or sulfur. ![]() Exposure, for example, can soften the surface of bronze gears, which are commonly used in worm drives.Īs a result, they should only be used when specified by the manufacturer. The majority of these agents are based on chlorine or sulfur, which can be hazardous to certain metals. This naturally implies a lot of additives, which can be dangerous if you’re not careful about the type of machine they’re put in. Extreme pressure gear oilsĮxtreme-pressure gear oils are engineered to withstand much higher levels of heat and pressure than other types. Oxidation protection prevents microscopic debris that inevitably separates the gears from oxidizing within the oil, thereby extending the useful life. ![]() Rust protection prevents gears and other machinery from corroding as the oil flows through the system, as well as providing some protection from moisture that may enter the machinery. The majority of gear oils will provide some level of rust and oxidation protection it’s one of the best ways to protect the gearbox and extend the life of a gearbox. They are classified as ISO grades 32-320. Rust and oxidation gear oil are formulated to reduce corrosion within the gearbox in which they are used. Below is the list of different types of gear oil: Rust and oxidation gear oil Many additives have disadvantages, which means that using the correct additive formulated for a specific operation is critical. Gear oils, like most specialized oils, contain a wide range of additives that are designed to handle a variety of situations.
