Part is still using the traditional oil, grease, and the fact that the industrial and mining condition is beyond the scope of oil, grease, easily happened bearing and other friction pair of bite or bite dead and cause severe parts wear and damage, frequently lead to equipment shutdown.To produce continuous operation, in addition to multiple devices in the original design required round outside, still must invest a lot of maintenance personnel.Severely limits the productivity, spare parts and the energy consumption greatly, has become the important obstacle of developing production.Automotive, cement production, and petrochemical enterprises are put forward to provide the special lubricating materials under complex working condition requirements.To this end, the inlay type of self-lubricating bearing composite materials research, highlight the characteristics of their own on the material formula and preparation technology, material performance has reached international advanced level, for the enterprise can solve the problem of lubrication under special working conditions, and has brought obvious economic and social benefits.But due to a variety of reasons more domestic enterprises has not been adopted, the situation is still there.
