Types of Gear Oil and Their Grades Explained

Gear oil is the most useful part of the gear as well as a lubricant designed for use in the manual gearbox, differential, transaxle, and transfer case present in the gearbox of any vehicle. It is made to keep the transmission system present in the gearbox running smoothly. Its main purpose is to escape the heat generated in the gearbox. The selection of gear oil is also very important for the gearbox.

For the selection of gear oil grades explained, it is necessary to take care of some things, in which it is necessary to pay attention to the viscosity of the oil as well as the additives and base oil of the oil. Viscosity actually helps to maintain the viscosity between the oil and the system, so gear oils are slightly thicker than other oils, which maintain their viscosity even in high heat or working heat, thereby maintaining better system performance.

In addition, the compound and base oil help to maintain optimal operating conditions of the system. Also, gear oil grades explained mainly helps in stopping the sliding process of the system. If we look at the components of gear oil, it mainly consists of dithiocarbamate derivatives and sulfur-treated organic compounds. We will see how many types of gear oil there are, which will help better in the selection of gear oil grades explained.

Types of gear oil-

The main topic of this article is the type of gear oil, which will help us choose the gear oil so that we can avoid the common problems in our gearbox.

Rust and oxidation inhibited (R&O) type gear oil grades explained – 

The main function of this oil is to prevent corrosion of the gearbox and also to protect it from oxidation. These oils are mainly used for operation under high speed, low load, and uniform loading. These oils are also useful for hydraulic systems where lubrication is required for a long period of time.

Compound type gear oil – 

Compound gear oil is primarily a mixture of acidless tallow or synthetic fatty acids. Which are used to prevent the gearbox from oxidation and rusting. It provides excellent lubrication to the surfaces of the system. that prevents the gear oil grades explained from slipping.

Extreme pressure type gear oil

The use of extreme pressure Gear oil is mainly made to protect the gearbox from external troubles. Its main job is to provide lubricant to the gearbox. It is mainly made by mixing elements like chlorine or sulfur, which cause it to heat more. And can easily withstand the pressure.

Synthetic type gear oil – 

Synthetic gear oils are primarily composed of polyalphaolefins and other additives that are primarily designed to withstand high temperatures as well as operating temperatures. Where other gear oils are not able to work easily, synthetic gear oil is used. Its viscosity is also better than the rest of the oil, as it is also thicker, due to the way it is used in loaded engines.

Types of gear oil and their description based on grades-

On the basis of grades, here gear oil is divided into three parts, which show the benefits of gear oil, which are mentioned on the basis of GL.

GL-1 TO GL- 3 types of gear oil – 

It is mainly used for manual transmission and axle. It can mainly withstand the pressure, heat, and friction of the gearbox, so gear oil of this grade is used.

GL-4 type of gear oil – 

It has the best amount of additives as well as it is used in common in all vehicles. It also plays an important role in maintaining the efficiency of the engine

GL-5 type of gear oil – 

This grade of oil is used for gears with high load resistance. They also contain a good amount of additives.

What are gear oil grades and how are they determined?

gear oil grades explained are determined on the basis of the SAE and ISO methods-

SAE type of grade system – 

The SAE grade system is mainly used for the determination of lubricants. SAE scales of 60 or more are used for gear oil. In this, the capital alphabet ‘W’ is used to determine the temperature of the cold. Similarly, a number is used to determine the temperature of the summer.

ISO type of grade system – 

It is a grading system based on the International System which denotes lubrication. It refers to the number related to the viscosity of the oil. Here, viscosity refers to the thickness of the oil as well as the resistance of the oil at the time of oil flow.

In this article, mainly gear oil has been described in a better way as well as its grades which are used in international and national form everywhere.
