DAITHERMO DTP
This environmentally friendly, lead-free polymer bearing material is injection molded from polyphenylenesulfide resin (PPS) with a special filler. It has sliding characteristics equivalent to those of polytetrafluoroethylene resin (PTFE). There is also a fiber-reinforced type, whose strength and heat resistance have been improved.
Product Details
Features
- Very low friction.
- No stick-slip effect.
- Use of flexible shaft.
- Availability of complex injection-molded shapes.
- Higher temperature capability than
fiber-reinforced DAIHILON bearing (to 160°C).
Major Applications
General industrial machinery, hydraulic equipment and equipment for air conditioning 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 2.9 | 6.9 | Below 15 | 60 | -40～180 | 0.05～0.2 | 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.
