IUS stainless steel plastic spraying bearing

Microstructure of Materials

1. Polytetrafluoroethylene and lipophilic fiber mixture 0.01-0.03mm
2. stainless steel back 0.7-2.3mm

Product Description

High corrosion resistance and wear resistance bearings composed of SF-1SS stainless steel material as the matrix and coated with PTFE on the surface. The material is especially suitable for strong acid, strong alkali, light load medium and low speed occasions, and its wear resistance is obviously better than that of single PTFE sleeve and graphite sleeve. At present, the product has been widely used in chemical acid-base flow meters, pumps, valves and corrosion-resistant sliding parts in marine industry.

technical parameters

Maximum bearing pressure: 100N/mm2
Applicable temperature range:-195~280 degrees Celsius
Maximum sliding speed: 2 m/s
Friction coefficient: 0.03~0.18
Maximum allowable PV value (dry):3.0N/mm2 .m/s
Maximum allowable PV value (oil):40N/mm2 .m/s

application features:

1. The mixture of PTFE and lipophilic fibers can form a good transfer film to protect the grinding shaft during movement.
2. Good wear resistance and low friction coefficient.
3. Good running performance and no shaft biting phenomenon.
4. It can be used in rotating, rocking and reciprocating motion.
5. Good corrosion resistance.
6. Because it does not contain lead, it can be used in food machinery, medical machinery and other green environmental protection equipment.
7. Typical uses: mainly used in medium acid and strong alkali occasions, such as: chemical medium acid and alkali flow meters, pumps, valves, printing and dyeing machinery,
Corrosion-resistant sliding parts in marine industry.
