DAIDYNE DDL02
This is an environmentally friendly lead-free bearing, the material structure of which consists of multiple layers of PTFE, porous intermediate layer and steel backing (similar to that of DDK05 dry bearings). Due to improved sliding and porous layers, boundary surface performance and fluid lubrication are also improved. Bearings less than 10mm in diameter can be produced with a 0.5mm wall thickness for lighter, more compact designs for solenoids and other applications.
Product Details
Features
- Excellent wear resistance due to boundary surface performance and fluid lubrication (two to three times that of DDK05).
- Excellent load resistance (two to three times that of DDK05).
- Lower friction than that of DDK05.
- Excellent cavitation resistance compared with DDK05.
- Bearings less than 10mm in diameter can be produced with 0.5mm wall thickness for lighter, more compact designs.
Major Applications
Shock absorbers, gear pumps, PS pumps, automotive parts and generial industrial machinery
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 49.0 | 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.
