DU/SF-1 Self-Lubricating Bushing
Overview
Made from premium low-carbon steel, copper powder, and PTFE composites through specialized processes. Delivers excellent physical and mechanical properties. The steel layer provides high load capacity; the copper layer transfers heat and enhances bonding; the PTFE-fiber mix forms a protective transfer film. Features wear resistance, low friction, long service life, low noise, and pollution-free operation. Ideal for hard-to-lubricate areas. Widely used in industrial applications.

Key Applications
FAQs
1. How Much Longer is the Life of Self Lubricating Bushings than Traditional Bushings?
According to test data, the life of a self lubricating bushing is usually 2-3 times that of a traditional lubricated bushing, depending on the application. For example, in the suspension system of a heavy-duty truck, a traditional bushing may need to be maintained every 10,000 km, while a self lubricating bushing can be extended to more than 30,000 km.
2. Do Self Lubricating Bushings need Regular Maintenance?
There is no need to add lubricant regularly, and its self-lubricating characteristics can maintain the whole service life. However, it is recommended to observe the wear of the bushing during each equipment inspection to ensure that there is no abnormality.
3. How High can the Self Lubricating Bushings Withstand?
Different materials have different temperature resistance. For example, PTFE base sleeves can withstand temperatures up to 260 C, while some composites are suitable for the range of-40 C to 150 C. You can select the specific model according to your application.
4. Is There any Special Tool Required to Install Self Lubricating Bushings?
The installation process is similar to that of a traditional bushing. It is usually pressed or hot fitted without special tools. However, it is necessary to ensure that the mating tolerance is in line with the manufacturer’s recommendation to avoid installation damage.
5. What is the Cost Effectiveness of Self Lubricating Bushings?
The initial cost may be 20-30% higher than the traditional bushings, but the long-term maintenance cost can be reduced by more than 50%. In the working device of an excavator, the use of self-lubricating bushings can save about 30% of the maintenance costs per year.
6. How to Choose the Right Bushing Model for My Application?
You should take the load, speed, temperature, environment and other factors into consideration . Myway can provide selection guidelines, or customizing according to your specific parameters.
7. How does the Self Lubricating Bushing Perform in a Dusty Environment?
The polymer coating of self lubricating bushing has good wear resistance and dustproof performance, making it suitable for dusty environments like construction site loaders. Tests show that in dusty environments, the self-lubricating bushing has a wear rate 40% lower than traditional bushings.
8. What are the Advantages of Self Lubricating Bushings over Bronze Bushings?
Self-lubricating bushings require no lubrication, are lighter in weight, have lower friction coefficient (about 0.05-0.1 vs. 0.15-0.2 for brass), and are more resistant to corrosion, especially in wet or corrosive environments.
