Tech Note No. 27 Cause and Analysis of Bearing and Shaft Failures in Electric Motors (Update - 4/99) Place in Section 9 of your EASA Technical Manual; note its location in Section 15, "Future Tech Notes." breaks down by oxidation. This process is a function of .
Over the years, we have been occupied in offering a wide range of Automotive Grease. Extremely utilized for lubrication of varied spares, this grease is processed using high quality chemical compounds in compliance with the industrial norms at vendors' end.
Not only is the lubricant's performance diminished, the acids produced can increase corrosive component wear. It is important to understand the process and root causes of oxidation and the warning signals generated by oil analysis. Managing and measuring lubricant oxidation is the key to the pursuit of lubrication excellence.

Jul 20, 2017· Prior Art Grease Oxidation Test. In the 1940's the desire for a readily applicable bench test for quality control of a grease formulation by measuring its oxidation resistance led to the development and publication of ASTM Test Method D942 in 1947—a test method which became a standard and continues to be applied. Ref.,

volatile oxidation products as the predominant factor controlling the lubrication life of grease in the cylindrical roller bearing tests. A critical base oil content of 50-60% by weight was identified. However, the failure process and the way in which grease degra-dation affects this will depend on the dominant mechanism of lu-

The FGDO spectrum shows two strong absorption bands long hydrocarbons chainof . The first peak s in the region 1375cmof 1080-1 represents the - 3 ...
Many conditions promoting accelerated oxidation co-exist in an engine, such as high temperatures, high pressures, a good air supply, agitation, the presence of metal catalysts and thin film exposure. The most significant of these conditions is the operating temperature, because rate of oxidation doubles for every 10°C increase in temperature.
Cooking oil is plant, animal, or synthetic fat used in frying, baking, and other types of cooking. It is also used in food preparation and flavouring not involving heat, such as salad dressings and bread dips, and in this sense might be more accurately termed edible oil.

Well-chosen oil bases of constant quality and packages comprising functional supplements place our products on top positions.
Compared to oil, grease tends to stay put within the bearing and requires less maintenance. It can also act as an effective sealant, keeping out contaminants and debris. The downside to grease, compared to oil, is that grease generates higher friction and has poor heat dissipation, making high-speed applications a challenge for greases.
AFIDA – Advanced Fuel Ignition Delay Analyzer – SA6000-0. Indicated Cetane Number Analysis. AFIDA is a revolutionary development providing you with a fully automated way of determining Indicated Cetane Number (ICN) of diesel and diesel related fuels.
This implies that in the chemical degradation process at high temperatures, the oxidation reactions initiate very rapidly (at least for the outer layer of grease exposed to oxygen). The rest of the maximum energy absorption is used to decompose the grease thickener and base oil by breaking down the chemical bonds of the grease component molecules.
GREASE BASES USED IN THE MANUFACTURE OF LUBRICANTS A lubricating grease is defined as a solid or semiliquid product representing a dispersion of a thickener in a liquid lubricant. Grease is used where it is required to hold the lubricating oil and appropriate additives together to lubricate those applications where an oil cannot be contained.
