[0002] Oil-free self-lubricating bearings are made by embedding solid lubricant graphite (black lead) into alloy materials such as high-strength brass, tin bronze, and aluminum bronze through an inlay process. The solid lubricant rubs against the shaft through frictional heat, forming excellent conditions for co-existence of oil and powder lubrication, which not only protects the shaft from wear, but also makes the solid lubrication characteristics permanent. Since the hardness of high-strength brass is twice as high as that of ordinary copper sleeves, its wear resistance is also twice as high, and its bearing capacity is high. During production, it needs to go through the processes of copper raw material smelting - casting blanks - blank surface processing (using lathe processing) - punching - installing graphite blocks in the holes - drying - cleaning and so on.
