Bearings are the most common reason for engine repair. But their premature wear is almost always caused by a removable cause. Let's look at why bearings fail.
Main reasons
- Problems with lubrication.Lack, excess or unsuitable lubrication.
- Contamination.Dust and moisture get inside, destroying the tracks.
- Misalignment.Misalignment with mechanism produces alternating loads.
- Imbalance and vibration.Accelerate fatigue failure.
- Overload.Axial and radial forces in excess of normal.
- Improper installation.Distortion or damage during installation.
How it manifests itself wear
| Symptom | Stage |
|---|---|
| Humming | Initial wear |
| Knocking, crunching | Destruction of tracks |
| Backlash, heating | Critical wear |
How to prevent
- Proper lubrication on schedule.
- Precise alignment during installation.
- Balancing to reduce vibration.
- Vibration control and diagnostics.
Timely replacement of bearings prevents the rotor from catching and expensive rewinding. Eliminating the cause (for example, misalignment) prevents the problem from returning.
