DAIDYNE DDK06
The material structure of DDK06 consists of multiple layers of PTFE resin, porous intermediate layer and steel backing (similar to that of DDK05 dry bearings). Due to the improved sliding and porous layers, boundary surface performance and fluid lubrication are also improved.
Product Details
Features
- Excellent cavitation resistance (approximately 10 times that of DDK05).
- Lower friction than DDK05.
- Excellent wear resistance at low and intermediate loads (three to five times that of DDK05).
- Excellent corrosion resistance.
- Wide range of applications.
Major Applications
Shock absorbers, general industrial machinery and automotive parts
Characteristics
| Specific Load MPa | Sliding Speed m/min | Service temp. Range °C (Min. to Max.) | Friction Coefficient μ | Tolerance of Foreign Particles | ||
|---|---|---|---|---|---|---|
| Normal | Max | Normal | Max | |||
| Below 29.4 | 137 | Below 180 (Boundary Lubrication) | Below 240 (Boundary Lubrication) | -200～280 | 0.01～0.1 (Boundary Lubrication) | Low |
- On the actual application, the best performance in all categories would not be expected to be exerted simultaneously.
- Thermalloy, Daislide and Dailubo have general-to-special grades to meet various customer needs.
