Lubricating greases are consistent lubricants made up of base oil and a specially chosen thickener. To increase certain properties, additives are added to the lubricating greases. Lubricating greases are structural elements, especially when used as long-life lubricants for lifetime lubrication. properties of a grease and therefore an understanding of thickening agents is necessary. The thickener in a grease is usually a metallic soap, but nonsoap thickeners are used as well. The soaps used are made by the saponification of animal fat or the neutralization of fatty acids. Soap-thickened greases comprise about 85% of all greases in use.
These test methods for analysis cover greases of the conventional type, which consist essentially of petroleum oil and soap. The constituents that can be determined are soap, unsaponifiable matter (petroleum oil, and so forth), water, free alkalinity, free fatty acid, fat, glycerin, and insolubles. Bearings in some applications use oil, but grease is the lubricant of choice for 80 to 90% of bearings. Grease consists of about 85% mineral or synthetic oil with thickeners rounding out the rest of the grease volume. The thickeners are usually lithium, calcium or sodium-based metallic soaps. Formulations for higher-temperature applications.
Lubricating Grease Institute) grade, which ranges from to 6. The consistency of a grease should be appropriate to the application, as it affects pumpability and ability to reach the areas to be lubricated. A NLGI 2 grade grease is the most commonly used in electric motor applications. Rationale: The SAE J Recommended Practice is intended to assist in the selection of grease used for servicing automotive applications. It provides general definitions and recommended test methods for use in determining proper grease selection. This revision updates the references to the current standards and test methods used for automotive service greases.

Lubricating grease is a mixture of a lubricating base fluid, a thickening agent, and additives. The thickening agent is a material that, in combination with the base fluid, produces the solid to semifluid structure.
Greases are used between close-fitting moveable surfaces both for sealing and lubrication. Sol Dushman in his book on. General Information for Refiners of Petroleum Regarding Tests of Lubricating Oils at the Engineering Experiment Station, Annapolis, MD.; Also Information Concerning Tests of Greases and Soluble Oils at the Laboratory of the Machinery Division, Navy Yard, N (Paperback) by United States Navy Dept Bureau Repair and a great selection of related books, art and collectibles.
The Lubricating Grease Guide serves as a source of basic information on lubricating grease and is a handy quick reference book. It contains material pertaining to a broad spectrum of grease related subjects and is written by technicians for the beginner or for the practitioner who wants to broaden knowledge.
The Lubricating Grease Guide includes a grease application. Lubricating greases can be defined as solid to semi‐fluid products of the dispersion of a thickening agent in a liquid lubricant. Thickeners not only transform liquid lubricants into consistent lubricants, they change the properties of the liquid lubricants also.
Interactions of thickeners and additives must always be considered. The definitive book on the science of grease lubrication for roller and needle bearings in industrial and vehicle engineering.
Grease Lubrication in Rolling Bearings provides an overview of the existing knowledge on the various aspects of grease lubrication (including lubrication systems) and the state of the art models that exist today. Lubricating Grease Manufacturing Technology Yuriy L. Ishchuk This book will solve difficulties faced by chemists working in R&D, Q&A of polymer related industries, and can be used as a reference book.
Book Description. Careful selection of the right lubricant(s) is required to keep a machine running smoothly.
Lubrication Fundamentals, Third Edition, Revised and Expanded describes the need and design for the many specialized oils and greases used to lubricate machine elements and builds on the tribology and lubrication basics discussed in previous.

The resulting lubricating grease is transparent and smooth, with a dropping point of ÂºF and a penetration of to at 77ÂºF. This product may be melted and cooled without change in structure.
A similar lubricating grease made with 20% of hydrogenated fish oil fatty acids has penetration of to and dropping point of ÂºF. The major content of the book are Food and Technical Grade White Oils and Highly Refined Paraffins, Base Oils from Petroleum, Formulation of Automotive Lubricants, Lubricating Grease, Aviation Lubricants, Formulation and Structure of Lubricating Greases, Marine Lubricants, Industrial Lubricants, Refining of Petroleum, Lubricating Oils, Greases.
According to the size of the vehicle, the size of the bearing varies. But all the bearings are made with the same material. So, if you use oil and grease to lubricate the bearings of the truck, you can also use the same material for lubricating the skateboard our recommendation is to use grease because it is a chronic and easy solution.
Unlike calculating grease volume, determining the optimum re-grease interval is slightly more complicated. There are several methods to do this but perhaps the easiest is to use the method first proposed by Lloyd “Tex” Leugner in his book, Practical Handbook of Machinery Lubrication (Maintenance Technology International Inc).
The Leugner. Poor lubrication accounts for over 36% of premature bearing failures. SKF lubricants are designed for your needs and tested for performance in real applications. Our experience with bearings, lubricants and applications helps us to offer the right lubricants for your applications and improve your overall lubrication scheme.

Boner. including greases. The thickener and the base oil are what give a grease its lubrication proper-ties, but it is mainly the base oil viscosity that determines the grease's lubrication capacity.
Viscosity depends both on temperature and pressure. The temperature is always stated when measuring viscosity, as viscosity decreases as the temperature.

But greases contain oil and thickeners, both of which also influence lifespan. Oil content is a measure of remaining life and can be quantified in a grease sample by atomic absorption spectroscopy or by solvent separation and weighing of the remaining oil.
Greases typically fail after losing about half their initial oil content. The lubricating fluid is usually a mineral oil, a diester or a silicone.
This chapter also provides tables, which illustrates some of the properties of greases; containing three types of fluids. All values and remarks are for greases typical of their class, some proprietary grades may give better or worse performance in some or even all respects. Considering all said above, lubricating greases should be regarded as high technology products, but this is often not the case.
Since the beginning of the 50ïs, so called multi-purpose greases have been available. These are lubricating greases that can meet most lubrication demands and is true, in about 80% of all applications.
The purpose of Lithium and Sodium lubricating greases production process, which described in this paper, comes for designing economic process with quite high quality. McGrew-Hill Book.
