Grease Lubricant: Grease is a semi-solid liquid mixed with thickener. Thickener holds the oil and provide resistance to flow while the oil does the lubrication.
Grease lubricant have traditionally been used and utilized to keep vehicles and machines to be well lubricated at all times. Different type of grease helps to reduce friction in various industrial appliances and help to produce different results based on their properties.
Cause of the different properties they possess, grease and lubricants are used in a variety of industries including automotive, mining, farming, construction and so on.
Types of Grease Lubricant And Their Uses
1. Lithium Grease
Lithium grease are the most commonly used type of grease cause of their extreme temperature and high melting point. They are known for their high durability, viscosity and stability. They are also characterized by their excellent lubrication, and protection against corrosion and extreme temperature.
Their ability to withstand high pressure and shock loads makes them suitable for industries including automotive, industrial, household and heavy metal appliances.
2. Calcium Grease
Calcium grease lubricant are one of the first grease manufactured for general and generic purposes. They are general purpose greases having great water resistance, protection from corrosion and great mechanical stability.
These greases lose their structure in high temperature, thus making them suitable for marine, industrial and agricultural applications.
3. Aluminum Complex Grease
Aluminum grease is a long life, heat resistance, water resistance grease having multiple advantages such as protection against oxidation, corrosion and wear and tear.
They are mostly suitable in Food industry but also provide excellent results when used in automotive, construction and farming industries.
4. Barium Complex Grease
Barium complex grease are high performance grease known for their properties such as mechanical stability, excellent water tolerance and resistance to high operating temperatures. They are also resistance to various chemicals.
They are mostly used in heavy load applications such as aeronautical, marine and manufacturing applications.
5. Bentone Grease
They are clay based lubricant and manufactured using Bentone clay. They are known as the non melt grease and thus have no known dropping point.
Their main properties include resistance from temperature change, great water and mechanical stability and impressive adhesiveness. They are typically used in ceramic, mining and construction industry.
6. Polyurea Grease
Polyurea grease lubricant is a premium multipurpose, high temperature, extreme pressure grease. They are specifically formulated to offer extreme lubrication requirement of service applications.
They gained popularity cause of their characteristics such as water resistance, great oxidation stability, durability and mechanical stability. Cause of their long life application, they are considered vital in steel plant and electric motors.
7. Sodium Grease
They are manufactured by using base oils with sodium soaps, thus providing with solid sheer stability, high dropping point and good lubrication.
But they have poor oxidation stability and water resistance. Also they have potential properties to be mixed with other greases in order to produce better quality grease.
Factors To Consider While Choosing Right Grease Lubricant
Base Oil
They represent the foundation of every lubricant and their types determines the overall performance. They provide lubrication and reduces fiction. There are mainly three types of base oil naming mineral, synthetic and vegetable oils.
Thickener
They are used to hold the oil like a sponge until they are needed. Various types of thickeners are used based on the consistency needed in the grease lubricant.
Additives
They enhance the features and qualities of grease an boost their performance and support oil capabilities. Moreover, certain dyes and pigments are added to each grease.
Viscosity
Viscosity determines the ability to remain stable and offering effective protection against friction. Higher viscosity provide great stability to grease. While lower viscosity grease are ideal for high speed applications.
Difference Between AP,MP And EP Grease Lubricant
AP Grease
AP stands for All Purpose which is a lithium-based multifunctional grease. Such greases are used in all types of automobile application. They are known for their properties which includes protection against rust and corrosion. Due to their high liquifying point it also provides great warm and solidness.
MP Grease
MP stands for Multi Purpose grease which is highly suggested for cars, horticulture and light transport applications. This oil gives the right required oil and allows the part to be well protected.
They are suitable to all kinds of applications and is an NLGI(National Lubrication Grease Institute) number 2 oil.
EP Grease
EP stands for Extreme Pressure. It is most stable and durable. They are more resistant than AP and MP grease lubricant. They are designed lubricate machine components where high pressures and heavy shock loadings are prevalent.
