| DESCRIPTION |
| SF-1S stainless steel corrosion-resistant bearing is a highly effective corrosion-resistant bearing made of stainless steel material as the substrate, with a spherical bronze powder layer sintered in the middle, and a low friction material mainly made of polytetrafluoroethylene rolled on the surface, which is formed by rolling. It has the characteristics of oil resistance, acid resistance, alkali resistance, seawater resistance, and wear resistance, and the PTEE material on the surface does not contain lead components. It is most suitable for use in corrosion-resistant sliding parts of food and beverage machinery, printing and dyeing machinery, chemical machinery, and marine industry. |
| Technical Parameter |
Maximum bearing pressure: 140N/mm2
Applicable temperature range: -195~+280 degrees Celsius
Maximum sliding speed: 2m/s
Friction coefficient: 0.04~0.20
Maximum allowable PV value (dry): 3.6N/mm2. m/s
Maximum allowable PV value (oil): 50N/mm2. m/s |
| Application features: |
1.PTFE、 The mixture of lipophilic fibers can form a good transfer film to protect the grinding shaft during exercise.
2. Good wear resistance and low friction coefficient.
3. Good running in performance, no shaft biting phenomenon.
4. Can be used in rotation, oscillation, and reciprocating motion.
5. Good corrosion resistance.
6. As it does not contain lead, it can be used in green and environmentally friendly equipment such as food machinery and medical machinery.
7. Typical applications: Mainly used in medium acid and strong alkali environments, such as acid and alkali flow meters, pumps, valves, printing and dyeing machinery in the chemical industry
