| Product description: |
| SF-1S stainless steel corrosion-resistant bearing is a kind of very effective corrosion-resistant bearing which is made of stainless steel as the matrix, sintered spherical bronze powder layer in the middle, and rolled with polytetrafluoroethylene as the main low friction material on the surface. It has the characteristics of oil resistance, acid resistance, alkali resistance, seawater resistance and wear resistance. The surface PTEE material does not contain lead. It is most suitable for the corrosion-resistant sliding parts of food and beverage machinery, printing and dyeing machinery, chemical machinery and marine industry. |
| Technical parameters: |
|
Maximum bearing pressure: 140N / mm2
Applicable temperature range: - 195 ~ + 280 ℃
Maximum sliding speed: 2m / S
Friction coefficient: 0.04 ~ 0.20
Allowable maximum PV value (dry): 3.6n/mm2.m/s
Allowable maximum PV value (oil): 50n / mm2. M / S |
| Application characteristics： |
|
1. The mixture of PTFE and lipophilic fiber can form a good transfer film to protect the grinding shaft.
2. Good wear resistance and low friction coefficient.
3. Good running in performance, no shaft undercut.
4. It can be used in rotation, swing 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 use: mainly used in medium acid and strong alkali occasions, such as: chemical medium acid and alkali flowmeter, pump, valve, printing and dyeing machinery
Corrosion resistant sliding parts of marine industry. |
