1. The mixture of modified polytetrafluoroethylene (PTFE) and lead (Pb) is 0.01~0.03mm, a wear-resistant material. During operation, a transfer film can be formed to protect the grinding shaft.
2. The copper powder layer of 0.2~0.3mm improves the bonding strength between PTFE/Pb and steel plate, and has good bearing capacity and wear resistance. At the same time, copper is a good heat conducting material, which can quickly transfer the heat generated during the operation of the bearing.
3. Low carbon steel 0.7~2.3 to improve the bearing capacity and heat transfer effect of bearings.
4. Copper/tin plating layer, copper plating layer 0.008mm, tin plating layer 0.005mm, so that the bearing has a good corrosion resistance function. |

| Application Characteristics |
1. No oil lubrication or less oil lubrication, suitable for occasions where oil cannot be added or it is difficult to add oil, and it can be used without maintenance or less maintenance;
2. Good wear resistance, low friction coefficient and long service life; 3. It can be used in the range of -195 ℃ ~ 280 ℃;
4. Good running performance, low noise, no pollution; 5. Thin-walled structure, light weight, can reduce the mechanical volume;
6. During operation, it can form a transfer film to protect the grinding shaft without biting the shaft;
7. The hardness requirement of the grinding shaft is low, and the shaft that has not been quenched and tempered can be used, thereby reducing the processing difficulty of related parts;
8. No water absorption, oil absorption, small thermal expansion coefficient, good heat dissipation, stable size;
9. The back of the steel can be plated with a variety of metals, so it can be used in corrosive media without rusting;
At present, it has been widely used in the sliding parts of various machinery, such as automatic mechanical equipment (telescopic, swinging, sliding, bending, rotating, rotating parts) hydraulic cylinder guide sleeve, gear pump, textile machinery, vending machine, plastic molding machine, die casting machine, rubber machinery, tobacco machine, fitness equipment, office machinery, hydraulic truck, automobile locomotive, motorcycle, agricultural and forestry machinery, etc. |
