It is the grading of lubricating greases by the National Lubricating Grease Institute. According to these grades, the lowest grade (grade 000) is for the softest friction conditions and the highest grade (grade 6) is for the hardest friction conditions. As the grade increases, the consistency of the grease goes from fluid to solid. You can contact our customer representatives for the right NLGI selection for your business.
Viscosity is the resistance of liquids to flow. Oils with low viscosity are characterised as “thin oil” and oils with high viscosity as “thick oil”.
Lubricants used in food processing and manufacturing must be completely non-toxic and meet the regulations for non-food compounds used in food production facilities. These strict guidelines are selected on the basis of use with incidental food contact NSF Class H1 or H2 (no risk of food contact). NSF certification assures users and food inspectors that the chemicals used is suitable for food safety. Certificates for our products can be found in the White Book Nonfood Compound Listings Directory at www.nsf.org.
Synthetic oils are chemically processed into the desired oil form, while mineral oils are the result of petroleum distillation.
Greases are used in all mechanical structures that come into contact with each other, such as rolling bearings, gears, mechanical materials that have friction at high temperatures, and so on.
There are three major substances in the chemical structure of grease. These are crude (base) oil, thickeners and additives.
The viscosity classification is determined according to the ISO VG class.
Abrasion occurs when two metallic materials rub against each other. Whichever of these materials has the higher density will abrade the other material, melting it over time.
Rust, also known as corrosion, forms on metallic materials, making it difficult for mechanical systems to operate and causing them to deteriorate over time. Such situations can cause disruptions to your business and result in serious damage costs. Rust inhibitors extend the life of your equipment.
Four ball tests are carried out to test the “high pressure” properties of a lubricant.
An oil not approved by the manufacturer can damage the machine parts you work with. You may think you are protecting your machine. However, the lubricating oil can lose its properties and structure at high temperatures. So you may be putting your machine at greater risk.
The primary function of lubricants in hydraulic systems is to transmit the force applied at one point to another point. This force must be transferred accurately and quickly. This process can be called the spreading of kinetic and potential forces. In this way, it prevents breakage. It also protects each contact point of these parts.
