| Q: |
Why is bearing type important? |
| A: |
There are several technical differences between ball bearing and sleeve bearings. What it all comes down to is the reliability, or Mean Time Between Failure (M.T.B.F.) In an identical environment, a ball bearing fan will continue to function or spin at the specified speed or airflow longer than a sleeve bearing fan. There are also two commonly used ball bearing fans, single ball bearing or double ball bearing. The double ball bearing have shown higher reliability rate than a single ball bearing or sleeve ball bearing fan. |
