When it comes to buying the proper type of grease to your particular person application requirements, it’s best to take several factors into consideration prior to making a last decision.
BASE OIL
Base oil represents the foundation of every lubricant and it’s price mentioning that its type determines the general performance of the grease in question. Three important types of base oils are mineral, synthetic, and vegetable oils. Synthetic oils are considered to offer the perfect outcomes by way of protection, performance, temperature and weather resistance, followed by good shear stability.
ADDITIVES
Additives are used to reinforce the options and qualities of each grease and increase its performance. The commonest additives are excessive pressure additives, oxidation, rust, and corrosion inhibitors, polymers used to increase adhesiveness, insoluble solids, and additives that provide elevated wear and tear protection. Additionally, sure dyes and pigments are added to every grease.
THICKENER
Thickeners are used to enable all grease components to bond higher, which will increase the overall effectivity of each grease. Types of thickeners which can be commonly used are simple and complex soaps, which are based on lithium, calcium, aluminium, sodium, and barium compounds. In addition, sure non-soap thickeners, similar to those based mostly on clay and polyurea, can be used to present the grease its consistency.
CONSISTENCY
Consistency is a property defined by the National Lubricating Grease Institute (NLGI) used to find out the level of softness or hardness of each grease. Each grease is assigned a selected NLGI number that goes from 000 to 6. These NLGI grades are then used to precise the level of consistency each grease has. So, as an example, NLGI grade 000 grease is completely fluid, NLGI grade 0 grease is described as very soft, NLGI 1 grease is soft, NLGI 2 grease is considered normal, NLGI 3 grease is firm, while NLGI 6 grease is defined as very hard.
VISCOSITY
Grease viscosity determines its ability to remain stable and provide efficient protection against friction. Higher viscosity provides greater stability when grease is exposed to heavy, gradual loads, while lower viscosity is ideal for high-speed applications.
TO SUM UP
As you may see, the type of grease you determine to use issues a lot.
Every lubricant has a unique set of characteristics that determine its consistency, viscosity, ability to stop friction, reduce wear and tear, protect against rust, corrosion, and oxidation, preserve mobility, and stop water and different contaminants from coming into contact with the equipment.
Take all these factors into consideration earlier than making a purchase and remember – the proper grease for you is the one that meets (and surpasses) all of the requirements you have.
