Composite liner due to the requirements of production process, industrial and mining enterprises of certain key equipment running in very bad condition.Due to the heavy equipment, high temperature, dust or air containing acid corrosion in gas CO, SO2, etc., bring many problems of equipment lubrication, friction and wear is serious, so far, most domestic enterprises is still using the traditional oil, grease, and the fact that the industrial and mining condition is beyond the scope of oil, grease lubrication, bearings and other composite bearing easily happened friction pair of bite or killed, cause severe parts wear and damage, frequently lead to equipment shutdown.And our factory research and development production of composite bushing suitable for 90% of the construction machinery industry, is now more than 300 hosts, rushed to the choose and buy products, and other self-lubricating bearings, sliding bearings and other products in the industry also choose to use the general public.

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.Therefore, the composite bushing for the enterprise can solve the problem of lubrication under special working conditions, and has brought obvious economic and social benefits.
