Track Bearings Bearing Failure Investigation Report

Track Bearings Bearing Failure Investigation Report


In this report, we will analyze the failure of track bearings in various applications. By examining the root causes of bearing failures, we aim to provide valuable insights for improving bearing performance and reliability.

Failure Modes and Causes

1. Fatigue Failure

2. Contamination

3. Improper Lubrication

4. Misalignment

5. Overloading

6. Corrosion

Fatigue Failure

Fatigue failure is one of the most common failure modes observed in track bearings. It occurs due to repeated cyclic loading, leading to the initiation and propagation of cracks in the bearing raceways. Factors contributing to fatigue failure include:

  • High operational loads
  • Insufficient bearing clearance
  • Poor surface finish

To mitigate fatigue failure, it is important to ensure proper bearing selection, adequate lubrication, and regular maintenance.


Contamination can significantly affect the performance and lifespan of track bearings. Common sources of contamination include:

  • Dust and dirt
  • Water
  • Foreign particles
  • Chemical contaminants

To prevent contamination, it is crucial to implement effective sealing mechanisms, conduct regular cleaning, and provide appropriate environmental controls.

Improper Lubrication

Improper lubrication can lead to premature bearing failure. Factors contributing to lubrication-related failures include:

  • Insufficient lubricant quantity
  • Incorrect lubricant viscosity
  • Contaminated or degraded lubricant
  • Inadequate lubrication intervals

Proper lubrication practices, such as using the right lubricant and following recommended maintenance schedules, can help prevent bearing failure.


Misalignment occurs when the bearing is not properly aligned with the mating components. This can lead to uneven load distribution, increased stress, and accelerated wear. Causes of misalignment include:

  • Shaft or housing deflection
  • Improper installation
  • Thermal expansion

To avoid misalignment-related failures, it is essential to ensure precise alignment during installation and consider factors that may cause misalignment in the operating environment.


Excessive loads on track bearings can result in premature failure. Overloading can be caused by:

  • Improper bearing selection
  • Unexpected changes in operating conditions
  • Equipment misuse or abuse

Proper load calculations, appropriate bearing selection, and adherence to recommended operating limits are crucial to prevent overloading-related failures.


Corrosion can severely affect the performance and longevity of track bearings, especially in harsh operating environments. Factors contributing to corrosion include:

  • Moisture and humidity
  • Chemical exposure
  • Improper storage conditions

Protective coatings, suitable bearing materials, and regular inspections can help mitigate the impact of corrosion and prevent premature bearing failure.


By investigating the various failure modes of track bearings, we have identified key factors that contribute to bearing failures. To ensure optimal bearing performance, it is essential to address these factors through proper selection, installation, lubrication, and maintenance practices. By following these guidelines, operators can maximize the lifespan and reliability of track bearings in their applications.
