SF-1S stainless steel corrosion-resistant bearings

SF-1S stainless steel corrosion-resistant bearings

SF-1S stainless steel corrosion-resistant bearing is a very effective corrosion-resistant material based on stainless steel material matrix, sintered corrosion-resistant alloy powder in the middle, low-friction material rolled on the surface of polytetrafluoroethylene, and the PTFE material on the surface does not contain lead.


■Material organization structure


1. Mixture of PTFE and lipophilic fiber 0. 01-0. 03mm

2. Spherical bronze powder 0. 2-0. 3mm

3. Steel back 0. 7-2. 3mm

■ Application characteristics


1. The mixture of PTFE and lipophilic fibers can form a good transfer film to protect the friction shaft during movement.

2. Good friction resistance and low friction coefficient.

3. Good walking performance, no biting shaft phenomenon.

4. It can be used in rotation, rocking and reciprocating motion.

5. Good corrosion resistance, with oil resistance, acid resistance, alkali resistance, seawater resistance and other characteristics.

6. Because it does not contain lead, it can be used in food machinery, medical machinery and other green environmental protection equipment.

7. Typical use: mainly used in medium acid, strong alkali occasions.

For example: acid and alkali flow meters, pumps, valves, printing and dyeing machinery, corrosion-resistant sliding parts in the marine industry.
