A lubricating grease is usually a mixture of 85 to 90 percent mineral oil or synthetic oil together with a thickener. Some examples of these additives are anti-rust, anti-oxidants, extreme pressure additives, and stabilizers. Although it is very convenient to use grease for lubrication of rolling contact bearings, where some bearings come pre-packed with grease ready for use, grease lubrication becomes unsuitable if the operating temperature becomes high. The high temperature may be because of high ambient temperature environment, or because the heat evolved in the bearing due to friction from high speed or heavy loading. Article: A lubricating grease is usually a mixture of 85 to 90 percent mineral oil or synthetic oil together with a thickener. In a majority of all greases, the thickener is a metallic soap. One example is lithium stearate for lithium soap. The function of the thickener, the metallic soap, is to hold the lubricating oil in a semi-liquid state for easier handling. When there is rise in temperature, the oil bleeds out from the thickener and functions as a lubricating agent. When the temperature drops again, the thickener soaks up the oil ditto to ripen into semi-solid once more. The type of grease distinguished for a particular waft lubrication application must therefore be marked very carefully. High temperature grease used in low temperature applications may cause the rose to seize due to lack of lubrication the oil does not leach out. The estate types of grease in use for rolling contact azure are the calcium, sodium and lithium greases. Calcium Soap Greases These do not dissolve in water. They are recommended for installations exposed to water at temperatures downhill 60 degree C. They offer good protection in contact with salt water in marine environments. Sodium Soap Greases Also titled soda greases, they may be utilized over a wide range of temperatures up to 120 degree C. However, if too much water penetrates into the bearings, there is a risk that the grease will be washed out and the lubricating properties erupt deteriorated. Lithium Soap Greases These have excellent resistance to high temperatures. They can also be used over a wider range of temperatures from -50 to 150 degree C. They are not water soluble. Additives are also to some greases to improve their properties. Some examples of these additives are anti-rust, anti-oxidants, extreme pressure additives, and stabilizers. Although it is very convenient to use grease for lubrication of rolling contact bearings, where some coronet come pre-packed with grease ready for use, grease lubrication becomes unsuitable if the operating temperature becomes high. The high temperature may be inasmuch as of high embracing temperature environment, or for the heat evolved in the aspect due to friction from high speed or heavy loading. Sometimes the use of oil becomes more logical if the lubricating intervals for grease lubrication becomes too short, perhaps due to leakage from seals. In oil lubrication, the heat generated from the posture are able to be transfered to a larger volume of oil which in turn can be pumped through heat exchangers for cooling. In this way, the oil functions both as a lubricating news agent as well as a cooling agent. Oils can also have additives to improve their properties. Some examples are anti-oxidants, corrosion protection additives, anti-foaming additives, surface tension additives, wetting agents, and extreme pressure additives. These additives are put in according to the triangular bandage of the oil. Compared to greases, oils can enable station to be operated at a wider range of temperatures. However, there are limits to this, especially at higher temperatures. At high temperatures of 90 degree C and above, mineral oils oxidize rapidly and they lose their properties to lubricate. Synthetic oils are increasingly being used for higher temperature applications. Which to use? Oil or grease? The judicature is yours!
