Auto water pump bearing manufacturer to introduce high-end bearing was monopolized by the us-japan driver for you

Bearings have high technical content, can be used as a measure of a country the important standard of science and technology, industrial power. In today's world of science and technology, industrial powers without exception is bearing research and development, manufacturing power. Rather than the industrial powers, industrial in our country is an important performance bearing industry is big but not strong. Bearing industry in China in 2012 sales of 142 billion yuan, the production is mainly to mid-range bearing, and high-end bearing mainly rely on imports. High-end bearing become 'short board' in the bucket principle used in aircraft engine matching top bearing with high reliability, high precision has become in the aircraft engine research and development in China is difficult to climb mount Everest. To launch the main bearing as an example, the main bearing is one of the key components of aircraft engine. Under the condition of high speed, high temperature, complex loading operation, main bearing quality and performance directly affect the engine performance, life and reliability. The aircraft engine is one of the key indicators of high reliability. To guarantee the reliability, one of the premise is to ensure that the engine bearings have long life - — Main bearing, the life of a military aircraft engine requirements in 3000 hours, commercial aircraft engine is more demanding, to reach tens of thousands of hours. In aircraft engine bearing working environment 'purgatory' can be used to describe completely, they should not only with tens of thousands of RPM speed high speed for a long time, even under various forms of extrusion stress, friction and ultra high temperature. In addition, for general structure parts, even a slight crack can ensure the safe use - — It called on major damage tolerance, and airlines launched main bearing such key driving part there is no damage tolerance, its in use process must not be allowed to appear crack and other forms of damage. And China's current aircraft engine main bearing life is limited, the bearing has become a 'short board' of barrel theory.
