The structure of the bearing is self-smooth. The bearing is developed on the metal conflict surface of the bearing base. The holes are ordered and large and appropriate, and the composite self-light slider made of molybdenum disulfide and graphite is embedded in the metal sleeve. Bearings, the friction area of ​​solid smoothing agent reaches 25-65%. The solid self-light slider can work normally under the high temperature of 280℃. However, due to its low mechanical strength, weak bearing capacity, and easy deformation, embedding it in the metal hole can suppress this defect, forming the metal part to play the role of load, and the smooth function of the light slider.

The smooth mechanism of this self-smooth bearing is that during the sliding conflict between the shaft and the sleeve, a part of the self-smooth data molecules are transferred to the metal surface of the shaft, filling the small unevenness, and forming a relatively stable solid smooth film , To form a solid smooth film between the grinding, to prevent the shaft and sleeve adhesion and wear. This rational connection summarizes the complementary advantages of copper alloys and non-metallic friction reduction materials, and is particularly suitable for the movement range in oil-free, high temperature, high load, low speed, anti-pollution, anti-corrosion, strong radiation environments, and It can be used under special working conditions in which water or other solutions are infiltrated and the base cannot be added with smooth grease.
