One thing you have to understand about grease is that it has a higher viscosity than oil. It's a semisolid lubricant that is built to protect heavy load applications, as well as gearboxes.
Machinery operating under very high temperature requires heavy lubrication. Grease provides a thick lubrication film, protecting the machinery from wear and tear. Worn out parts of machinery are also best protected from further damage by the application of grease oils.
Then of course you can't forget that grease actually reduces the noise created by various parts. Machines that are used all the team need to have grease oils applied. The insulated film is initiated to provide protection from long term deterioration issues.
When you take a lubricant and mix it with a thickener you will get grease. The most common thickener is soap, and the usual lubricants are mineral oils with various viscosity levels. Sometimes metallic soaps are utilized because they contain calcium, lithium, barium, and aluminum. However, sodium soaps taken advantage of by several companies.
There are additives and modifiers in grease oils that help improve functionality. The four most used are; anti-wear agents, oxidation, pour point depressants, and rust inhibitors. During extreme pressure conditions these help enhance the overall usage. Keep in mind; there are times when dyes, friction reducing agents, and pigments are utilized.
Below you will find a short list of how greases are categorized:
Light Grease
One of the main components of this grease is copper. It provides a thin but strong film on movable parts. Light grease oils are also applied on machine parts that are subject to conditions of high temperature such as brake pads and sliding break systems. It is also applied on nuts and bolts.
Heavy Grease
This is used to protect machines for a longer period of time. Light grease would wear off too quickly, and heavy grease is thick, as well as waterproof.
Multipurpose Grease
This product is made from combining two or more different grease oils. Its combined composition makes it suitable for most applications, with the exception of CV joints. However, it lacks water-resistant and corrosion inhibiting properties.
Water Pump Grease
This type of grease is made from calcium components. It's used to protect parts that are situated under water. The biggest benefit is that it can handle both high and low temperatures. The best use for it is on water pipes that are completely under water.
Medium Grease
This form of grease has graphite components within it. The medium consistency is considered to be a water-resistant grease oil. If you use it make sure it's on something that is exposed.
Rubber Grease
It is made from vegetable oils and is usually red in color. Rubber grease is applied on rubber seals.
Synthetic Grease
Synthetic grease is generally applied on high performance applications. It has a longer ‘life’ than other types of grease oil.
