Why bearings fail

Why bearings fail

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

  1. Problems with lubrication.Lack, excess or unsuitable lubrication.
  2. Contamination.Dust and moisture get inside, destroying the tracks.
  3. Misalignment.Misalignment with mechanism produces alternating loads.
  4. Imbalance and vibration.Accelerate fatigue failure.
  5. Overload.Axial and radial forces in excess of normal.
  6. Improper installation.Distortion or damage during installation.

Backlash, heatingCritical 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.
