The structure combines the characteristics of the copper alloy and the lubricating material, and can be used in situations where the oil film lubrication is difficult to form and the lubricant can not be added because the condition is limited. The general matrix containing lubricating material through the bearing inner and outer diameter, equipment in the operation process, through the friction lubricating material and shaft friction, lubrication materials and lubricating oil oozing, excellent conditions for the formation of oil film lubrication between the bearing and shaft wall, both to protect the shaft wear, and solid lubrication characteristics last forever
