Self-lubricating ceramic bearing

The utility model discloses a self-lubricating ceramic bearing which comprises a cylindrical bearing body, the bearing body is provided with an axial through bearing hole, and the bearing hole and the bearing body are coaxially arranged; the roughness of the inner circumferential surface of the bearing hole is smaller than 0.1 micrometer, and the axial length of the bearing body is 5-16 mm. The self-lubricating ceramic bearing is simple in structure and easy to assemble and use, lubricating oil does not need to be frequently added in the use process, the workload of later maintenance is simplified, the self-lubricating ceramic bearing has better stability, the overall quality of products can be improved, and the production cost is reduced. And the cable also has the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, magnetoelectric insulation resistance, long service life, high rotating speed and the like. 本实用新型公开一种自润滑陶瓷轴承，包括轴承本体，所述轴承本体呈圆柱状，所述轴承本体设有轴向贯穿的轴承孔
