Industrial gear oils are designed for severe-duty conditions requiring lubricants with high film strength, oxidation stability, rust protection and water separation. It is suitable for use in all types of enclosed gear drives. These are required to function in the presence of large quantities of water, as found in steel mills, which when mixed with oil can cause rust, corrosion, and a loss of gear protection. These gear oils are also used in the highly contaminated environment of a mine or quarry, while sustaining high loads, speeds and operating temperatures.

Industrial generator is a synchronous machine used to convert kinetic energy into the electrical energy. It general uses electromagnetic induction. The task of converting the electrical energy into mechanical energy is accomplished by using a motor. It is used for industrial applications requiring high voltages. It operates on the principle of Faraday's law.
