Deterioration is the undesirable chemical alteration of mineral and synthetic products . lubricants fuels during operation and storage triggered by reactions with oxygen formation of peroxides hydrocarbon radicals heat light and catalytic influences of metals and other contaminants accelerate oxidation. Formation of acids and sludge. - Anti-Oxidants AO retard the deterioration process. Dispersants Additives in lubricating oils which hold fine dirt particles in suspension until they are filtered out or removed when the oil is changed. Dispersion Lubrication Method of applying the lubricant. The rolling bearing is dipped into the dispersion bath disperging agent and grease . After the disperging agent has evaporated a 1 to 100 pm thick lubricant layer remains on the bearing surfaces. Advantage minimum friction. Drawback reduced grease service life. Distillates Hydrocarbon compounds obtained from crude oil distillation. Drop Point Temperature at which a grease sample when heated under standard test conditions passes into a liquid state flows through the opening of a grease cup and drops to the bottom of the test tube. Grease DIN ISO 2176. FAG I 60 Dry Lubricants Substances such as graphite and molybdenum disulphide suspended in oils and greases or applied directly. Dynamic Viscosity - Viscosity. Emcor Method Testing of corrosion preventing properties of rolling bearing greases according to DIN 51 802. Emulsibility Tendency of an oil to emulsify with water. Emulsifiers Additives which help to form an emulsion. Emulsion Mixture of insoluble substances usually mineral oils with water which is activated by emulsifiers. Elastic Behaviour of Lubricating Greases The elastic properties of lubricating greases indicate the suitability of a grease for centralized lubrication systems DIN 51 816T2 . EP Lubricants Extreme .
