| SF-1X oil-free lubricated bearing |
| Material Structure |
   
|
A mixture of modified polytetrafluoroethylene (PTFE) and lead (Pb) with a thickness of 0.01~0.03mm is a wear-resistant material that can form a transfer film during operation to protect the grinding shaft.
2. The copper powder layer of 0.2-0.3mm enhances the bonding strength between PTFE/Pb and steel plates, providing excellent load-bearing capacity and wear resistance. Copper is also a good thermal conductive material that can quickly transfer the heat generated during the operation of bearings.
3. Low carbon steel 0.7~2.3, improving the bearing's load-bearing capacity and heat transfer effect.
4. Copper/tin electroplating layer, with a copper coating of 0.008mm and a tin coating of 0.005mm, provides the bearing with excellent corrosion resistance. |

| Application Features Application CHARACTER |
1. Oil free or low oil lubrication, suitable for situations where refueling is impossible or difficult, and can be used without maintenance or with minimal maintenance;
2. Good wear resistance, low friction coefficient, and long service life; three Can be used within the range of -195 ℃ to+280 ℃;
4. Good running in performance, low noise, and no pollution; five Thin walled structure, lightweight, capable of reducing mechanical volume;
6. During operation, it can form a transfer film to protect the grinding shaft without biting the shaft;
7. The hardness requirement for grinding shafts is low, and shafts that have not been quenched and tempered can be used, thereby reducing the difficulty of machining related parts;
8. No water absorption or oil absorption, low thermal expansion coefficient, good heat dissipation, and stable size;
9. The back of the steel can be electroplated with various 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 hydraulic cylinder guide sleeves, gear pumps, textile machinery, vending machines, plastic molding machines, die-casting machines, rubber machinery, tobacco machines, fitness equipment, office machinery, hydraulic handling vehicles, motorcycles, agricultural and forestry machinery, etc. in automated mechanical equipment (telescopic, swinging, sliding, bending, rotating, revolving parts). |
