Grease and lubricants are used in every type of machinery. Their applications are increasing day by day. And obviously, they are very useful in daily life.
Most people have the wrong idea about grease and lubricants. They think that lubricants and grease are same. But it's not that. They are half wrong. Here, I am going to show the difference between grease and lubricant. Here we will have a deep insight of lubricant and grease so that you can quickly catch the difference.
In our daily life and in many sector, lubricant and grease are used. So, it's necessary to use them properly. You can be mistaken when you use them without knowing their application and also by treating them as same.
For perfect application of knowing the difference between them is very necessary. For the next few moments, we will have a deep insight of these two. So, let's get started.
Lubricants work for minimizing friction between moving pieces and for minimizing the passive resistance of the stationary parts of metals. All kind of lubricants is manufactured from crude oil after a certain stage of refining.
There are some types of lubricants. Such as: solid (graphite, Teflon), semi-solid (silicon gels,grease) and liquid or fluid (oils).
Obviously, every lubricant may differ compared to their performances and characteristics. But all of them have the same main component in common, and it is "base oil". Lubricants mainly contain between 75% and 85% base oil of synthetic origin or mineral.
Lubricates are used for lubrication. Reducing friction (rubbing or deformation), preventing pieces from wear is its primary function. Also, it reduces or absorbs shocks and protect from corrosion.
Without any doubt, lubrication isolates components from contamination. In another word, lubrication gets rid of contaminants.
Greases are things which mainly consist of 0 to 95 % base oil (synthetic, mineral or vegetable), 0 to 10 % additive as we mentioned previously. To increase the viscosity and thickness 3 to 20 % thickening agents are mixed with base oil. The base oil makes it smooth and thickening agent makes machinery lick proof.
Greases have high efficiency standing out in particular for their great adhesion to the surfaces of metals to be lubricated. Also, as they are insoluble in water they have the ability to prevent sharing and therefore they last longer.
This is most noteworthy that you can't heat grease more than 300 degrees because this will cause separation of thickener from the base oil. And above this temperature, aluminum or copper based coatings and thermal pastes are more suitable.
The good thing about grease is that, to its lubricating role (reduction of energy losses and mechanical fatigue due to friction), grease automatically creates a barrier (waterproof) against external elements like dust, heat, water, solvents etc.
I know from above information that, greases are one type of lubricant. So, I can say that every grease is lubricants but all lubricants aren't greased. And this is the main difference between grease and lubricant.
Grease is one kind of oil which has included a soap-like additive. The soap is actually added to thicken the oil. And the benefit about that is, it will stay or settle better to bearing surfaces or other areas. Also, some elements such as lithium, calcium, and copper are addedfor the purpose of which the grease is intended.
Greases are generally designed for applying on bearing surfaces,cantilever bosses, cables, seat posts, threads, and stems.Greases are applicable in other sectors, where there is a barrier between two materials is desirable.
Besides, lubricants are applicablein wide range compared to grease. Lubricants are used in places where friction may occur such as chains, levers, and gear levers. And obviously, lubricants do everything that greases do.
So, compared to the working sector, lubricants are superior to grease. This is also a noticeable difference between grease and lubricant.
Now you are acutely aware of lubricants as well as grease. Now, you can differentiate lubricant and grease on your own. Now need to apply your knowledge whenever it is necessary.
