 Grease making is no longer considered to be an "art". Guesswork and instinct have been replaced by scientific formulation in modern laboratories to meet the many general and special needs of industrial machinery. Fully Formulated greases purchased from reliable suppliers have uniform batch-to-batch quality and possess typical standardized characteristics, but actual performance in service cannot be assured on the basis of specifications and characteristics alone. Greases under development are subjected by grease manufacturers to a large number of physical, chemical, and mechanical tests to simulate actual operating conditions. This assures that consumers will receive high-quality, dependable products which are suitable for the intended application.When To Lubricate The choice between the use of a fluid lubricant or a grease is made by the machine designer, and will depend on the expected operating conditions as well as the lubrication system to be used and the properties of grease make them the preferred lubricants. Greases are frequently used to lubricate parts of machinery which are difficult to reach during operation, providing effective service for extended periods with only infrequent lubricant changes. They are especially suitable for lubricating gears and bearings under very severe or extreme operating conditions such as high operating temperatures, heavy loads, shock loading, low speed combined with high pressure, and intermittent operation. A grease will tend to "stay put"in its housing and not leak or drip out around the seal. This helps to keep out dust, dirt, water, and corrosive gaseous or liquid contaminants. There can also be significant cost savings. Because grease will "stay put", grease seals are less complex than oil seals, and are therefore more economical. In addition pumps and sumps are not required for the lubrication of bearings and gears with grease. This can often mean decreased equipment complexity and significantly reduced space requirements. Grease Composition and Properties Because of limited knowledge about the performance and properties of greases, early industrial greases were formulated for a single purpose or for a limited number of applications. Speeds and operating temperatures were generally low, so that simple greases of appropriate consistency (thickness) could be used for general lubrication. As industrial equipment has evolved and become more complex, operating conditions have become more severe, Higher operating speeds, temperatures, and loads have dictated the need for higher performance greases. At the same time economic considerations call for the use of multipurpose greases wherever possible. However, specialty greases may be needed for unique applications. |
