| Product Description |
| SF-1W sliding bearing is a new product developed based on SF-1 material according to international environmental requirements. This product is not only widely used in general machinery, but also particularly suitable for food machinery, pharmaceutical machinery, and tobacco machinery. Its lead-free effect meets European hygiene standards and is the direction for the development of oil-free lubricated bearings. |
| Technical Specifications |
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 fibers can form a good transfer film to protect the grinding shaft during movement.
2. Because it does not contain lead, it is harmless to the human body.
3. Has excellent load-bearing capacity and wear resistance.
4. Copper and steel plates have good thermal conductivity.
5. The surface electroplating layer has good corrosion resistance.
6. The product has been widely used in food machinery, medical machinery, tobacco machinery, beverage machinery, and other green machinery. with
With the gradual development of international environmental protection, SF-1W will be a substitute for SF-1 products. |
