Bearing is a kind of common sliding parts in mechanical industry. Graphite bearing is a carbon bearing developed on the basis of metal bearing with the performance requirements of mechanical equipment. Carbon bearings have different characteristics from metal bearings, such as self lubrication, high temperature resistance, corrosion resistance, light weight, etc. With the development of science and technology, graphite bearings have also been further expanded, and bronze graphite oil bearing and inlaid graphite bearing have been manufactured. It provides more space for bearing selection under various working conditions and meets the requirements of different technical conditions. In addition, carbon composite bearing will be the development direction of bearing materials in the future due to its designability and unique material functions.
