Explanation: EP 2 grease is used lubricating gears. This gear can handle heavy, suddenly applied loads in bearing application. High-temperature grease is used in weld boxes and other equipment that is subjected to a temperature above 200°F. Chain and open-gear grease are used on chain couplings, chain-driven components and open gear drives.

Explanation: ISO grade 460 (SAE 140) Gear oil is used in sealed gearboxes. Gear oil has extreme pressure additives that strengthen the non-detergent oils to withstand heavy loads found in gears and gear drive systems.

5. Petroleum based lubricants.

Explanation: Chemical solutions are one of the fastest growing roll forming lubricant family. They are economical, environmentally safe, easy to handle, and are ideal for use on coated, galvanised, cold roll steel, aluminium, and in some instances, stainless steel.

Explanation: The soap-type solutions are used for heavy-duty roll forming. Non-ionic type solutions are excellent for roll forming aluminium and coated components and extreme pressure-type are used for high strength alloys.

Explanation: Evaporative lubricants are used for roll forming of painted, coated, and vinyl surfaces as well as ferrous and non-ferrous materials. They are applied using the proper type of airless spray system.

Explanation: micro-emulsions provide some film strength from the combination of emulsifiers, water-soluble corrosion inhibitors, wetting agents, organic and inorganic salts, and sometimes extreme pressure agents.

Explanation: Macro-emulsions contain an oil-based lubricant, such as a mineral or compounded oil in the form of suspended droplets, which have been dispersed with emulsifiers due to which they become milky white appearance. Therefore, they are sometimes misleadingly called soluble oils.

Examples of additives: Rust and corrosion additives, EP additives, etc.

Explanation: Nitrates are usually used as rust or corrosion inhibitors; whereas compounds of sulphur, chlorine and phosphor are extreme pressure additives.
