What are the differences between greases, oils & lubricants?
Greases, oils & lubricants are different types of liquid-based products used to protect various mechanical components from contamination, and corrosion caused by friction, thereby maintaining them for longer.
Lubricants come in different varieties and are generally water-based, mineral-oil based or synthetic-based.
Greases & oils are important lubricants used widely in facilities, cleaning & maintenance. Greases are semi-solid lubricants composed of base oil, thickener, and specific additives based on the intended application. Oils are similar to greases but lack the thickener and come in liquid form. They are also composed of base oil and specific additives. The additives that are present in the oil depend on its intended use.
Importance of greases, oils & lubricants
The main purpose of greases, oils & lubricants is to protect mechanical components and machinery from contamination and wear due to continuous friction. They are important products for almost every industry and are commonly used in cars, factory machinery, moving parts, hydraulics, bearings, heavy-duty machinery, gears, and so on.
Most importantly, greases, oils & lubricants offer resistance against corrosion, water, oxidation, high temperatures and low temperatures. Naturally, they ensure the durability and efficiency of machinery and mechanical parts.
Best practices while purchasing greases, oils & lubricants
Buying the wrong types of greases, oils & lubricants can cause serious damage to machinery. Hence, it is important to consider the following factors:
Check the specific function of the lubricant. Lubricants have a wide range of functions and applications and can be used to control & prevent friction, corrosion, contamination, temperature, and power termination.
Look at the ingredients before you buy. Each type of lubricant contains special additives that serve specific purposes. Find the one that fits your given application.
Thoroughly check properties like the viscosity of the lubricant, consistency, shear stability, runout, weight, kinematic viscosity, durability, etc. to make sure these are suitable for your application and component.
