Page 7High-Performance Lubricating Greases1. General criteria for selecting a greaseA grease is a semi-fluid product which consists of dispersion of a thickening agent in a liquid lubricant,together with other ingredients that give the grease special properties (additives).The structure of the grease allows the lubricant to remain in a solid state until the shear stress between surfaces reaches acertain level, and the grease begins to flow and becomes a mobile compound.Lubricating greases may be selected on the basis of a number of different criteria.Some of these criteria are shown below:1.

High-Performance Lubricating GreasesPage 8To select the correct grease, the three components that it is comprised of must be taken into account: the lubricating baseoil, the thickener, and the additives.The most important properties to be considered when choosing the greases are as follows:ConsistencyBase oil viscosityEP and anti-wear additivesDropping pointResistance to high/low temperaturesResistance to environmental working conditionsCONSISTENCYThe consistency determines the thickness of the grease and is influenced by the type and percentage of the thickener used.It also provides the structure (like a sponge) that stores the lubricant base oil.The NLGI (National Lubricating Grease Institute) grades show the penetration of a standard cone in a sample of grease undercertain conditions. A low value indicates a high level of penetration, while a high NLGI value will be obtained for a hardergrease.As general recommendations, we use consistency grades 1 and 2 for general lubrication, the lowest grades (0 and 00) forcentralised systems and gear lubrication, and the highest grades (3) for elements in high temperature conditions.

BriquettesBASE OIL VISCOSITYThe selection of the base oil viscosity will depend on the load and speed conditions of the application, as well as the degreeof separation of the oil and pumpability of the grease.Greases formulated with high viscosity base oils offer advantages such as greater adhesion and water resistance, as well aslower oil separation, and are therefore well suited to applications with high loads.However, low viscosity base oils give the grease better heat transfer and enhanced performance at low temperatures andare therefore the best option for equipment with light loads and high speeds.ISO VG([email protected]ºC)APPLICATIONS100High speeds Electric motors150Wheel bearings220Paper industry Industrialapplications460Paper and steel industry1000Mining equipment1500High loads/vibrationsLOADSPEEDOILSEPARATIONPUMPABILITY

High-Performance Lubricating GreasesPage 10DROPPING POINTThe dropping point is defined as the temperature at which the grease changes from a semi-solid to a liquid state. It is aqualitative indication of the grease’s resistance to heat in those instances where a semi-solid lubricant is required.Complex soaps [lithium complex, aluminum complex, calcium complex sulfonate, etc.] have higher dropping points thantheir simple soap equivalents.RESISTANCE TO HIGH AND LOW TEMPERATURESThe maximum working temperature is determined both by the nature of the base oil and the thickener used.The base oil’s viscosity and the grease’s consistency are decisive in terms of their performance at low temperatures.DIN 51825 classifies greases according to their operating temperature range.AW AND EP PROPERTIESThe presence of an adequate layer of lubricating oil to prevent direct contact of the surfaces protected by the greaseis essential. For this purpose, it is necessary to select the right viscosity of the base oil, as well as special anti-wear andextreme-pressure additives.RESISTANCE TO ENVIRONMENTAL WORKINGCONDITIONSThe presence of humidity or extremely dirty environments has a huge influence on the nature of the grease to be used.Aspects such as anti-rust or anti-corrosion protection, water resistance, biodegradability, and equipment noise limitationrequirements are crucial when it comes to selecting the right grease.
