FAG Bearings offline test car

To understand parts life testing methods. FAG bearing life testing is destructive testing, life measured out, parts will be scrapped. Therefore, part of the life of the test method used is sampling. In a large number of materials and processing conditions in the same part a small sample taken for testing, according to test results estimated life of these parts. Because factory inspection of each product is not necessarily to achieve life expectancy.
 But also understand the meaning of parts life indicators. Life is a probabilistic indicator indicators, such as the most used car rolling, its life is in intact rate basis. 1000 taken as a sample of a bearing life test, the following situations may occur: (1) after 100 hours of operation of bearing damage, after 100,000 hours running two Bearing test machine damaged after running 150,000 hours 5 bearing damage, running one million hours after 10 clutch bearing amage ...... So, with 95% of the intact condition was rated life of 150,000 hours, with 90% of the intact condition was rated life of 1 million hours. In other words, SKF Bearings your car fitted with the rated life of 1 million hours of FAG bearings, running 100 hours on the probability of damage is consistent with the indicators.
In summary, the component life indicator is a calculated value, this value is selected according to the designer Matching parts. However, the so-called qualifying parts is sampled at a good rate of compliance samples under the conditions of the arrival of the rated life. Thus, the life of the parts is a probability value. On the whole batch of parts, being able to meet the design requirements, and specific to each part, its life may be bigger than the ratings may also be smaller than the rating. FAG Bearings anywhere in the world can not be without a brand of car failure, the difference is more or less problems, the construction of modern cars is much more complex than in the past, tens of thousands of parts, some problems occur during use is not surprising. Although Mercedes-Benz brand-name goods, but it will not guarantee no problems per vehicle each part. Do not think that is a brand new car or a car you can sit back and relax, but it is a relatively low probability of failure only. It seems, absolutely nothing wrong car really is not easy to buy.
