1. The bushing is considered to be the friction coefficient from the angle of friction loss, the smaller the friction coefficient as the bearing material, the better the wear coefficient of the graphite bearing lubricating bearing show;
2, from the structure, graphite is a solid material, can be oil-free lubrication, reduce the graphite lubrication bearing less lubrication system, thereby reducing the failure rate;
3. Graphite has high chemical stability;
4, the price is cheap, the versatility is strong; if the metal is used as the bearing, according to the graphite bronze bearing you said that the situation should be operated at high temperature, obviously the ordinary material is not good, the material with high temperature strength needs to be customized, the price is not several times, a few Ten times more than a hundred times can not be done, the first thing is not easy to find.
