Material organization:
1. Modified polytetrafluoroethylene (PTFE) and lead (Pb) mixture 0.01~0.03mm, a wear-resistant material, the operation process can form a transfer film to protect the grinding shaft.
2. Copper powder layer 0.2~0.3mm to improve the bonding strength of PTFE/Pb and steel plate, has a good bearing capacity and wear resistance. At the same time, copper is a good heat conduction material, which can quickly transfer the heat generated during the operation of bearings.
3. Low carbon steel 0.7~2.3, improve bearing capacity and heat transfer effect of bearings.
4 Copper/tin coating, copper coating 0.008mm, tin coating 0.005mm, so that the bearing has good corrosion resistance.
Application characteristics
1. Oil-free lubrication or less oil lubrication, suitable for unable to refueling or difficult refueling occasions, can be used without maintenance or less maintenance;
2. Good wear resistance, small friction coefficient, long service life; 3. Can be used in the range of -195¡É ~ +280¡É;
4. Good closing performance, low noise, no pollution; 5. Thin-walled structure, light weight, can reduce the mechanical volume;
6. The transfer film can be formed during operation to protect the grinding shaft without biting the shaft.
7. The hardness of the grinding shaft is low, and the shaft without tempering treatment can be used, thus reducing the processing difficulty of related parts;
8. No water absorption, oil absorption, small thermal expansion coefficient, good heat dissipation, stable size;
9 steel back can be electroplated a variety of metals, so it can be used in corrosive media, will not rust;
At present, it has been widely used in all kinds of mechanical sliding parts, such as automatic mechanical equipment (telescopic, swing, sliding, bending, rotating, rotary 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 carrier, steam engine car, motorcycle, agricultural and forestry machinery
