Industrial lubrication involves some concepts which are not entirely correct, and we may refer to them as myths. When it comes to lubricants, most clients and plant owners don't realize the significance of knowing the truth about these myths. There are six common myths that we need to debunk to spread awareness and understanding of proper lubrication.
1. There's no difference among lubricants
All lubricants play the role of lubricating and reducing friction in machinery, that's true. But this does not mean that they don't differ at all in their composition, such as suitable operating conditions like temperature, for instance. Every lubricant possesses specific properties and composition to perform a particular function under particular operating conditions. This is why one lubricant can't replace another with a different composition and function to perform.
2. Over-lubrication is beneficial
The concept that oiling in excess maximizes the advantages is another myth that we need to debunk. People think that more lubricant will bring more benefits to the machine and the business. The truth is absolutely the opposite. If you put an excessive volume of a lubricant in a machine, it will start damaging the machinery's seals and components. For instance, exceeding volumes of grease may cause the bearings to jam and stop working.
Proper lubrication of a machine requires a specific quantity of the lubricant for being effective. There are markings on the machine which says how much oil must be inside the machine. The maximum and minimum limits are there to follow strictly to avoid damage to the machine and loss of money.
3. Colored grease is better than transparent
When it comes to greases, there are different colors. The concept that red, blue, or any other grease color indicates that it's higher in quality, is not valid. The color of the grease has nothing to do with its performance. It's the composition, viscosity, and other properties, but not the color. You must focus more on the performance capabilities under the relevant operating conditions and not on the appearance and color.
4. Tackiness and stringiness matters
Another myth is that If the lubricant or the grease has a sticky and stringy appearance, it promises high quality and effectiveness for all machinery and every operating condition. Tackier lubricant does not mean it will be the best for your machine. Some machines and specific operating conditions require a tackier lubricant, while others may need a less tacky lubricant. There is a need to see the characteristics of the lubricant more than its sticky texture to decide whether it'll suit your specific case or not.
5. Food grade NSF H-1 products are not as good as NSF H-2
Talking about a myth regarding food-grade oils is that the NSF H-2 is always superior in quality as compared to NSF H-1. This is also not the case. These are two separate types of food-grade oils, and the number 1 and 2 don't represent that 2 is better than 1 because it came to the market later on.
6. There isn't any compatibility issue among lubricants
When users decide to change the brand or grade of a lubricant, they believe that all lubricants are compatible. If we take the example of grease, manufacturers use different materials like silica gel, lithium, aluminum, and their respective complexes. These different materials aren’t compatible with each other. If you mix the two types of greases up, the results can be devastating instead of advantageous.
