Average Lifespan
After continuous operation at a specified constant temperature, the average lifespan can be estimated if 90% of the units are still operational after testing.
| Sleeve Bearing | Test Temperature | Test Time (hours) |
|---|---|---|
| Hydraumatic | 25°C | 33,000 |
| Hydraumatic | 40°C | 25,000 |
| Hydraumatic | 60°C | 20,000 |
