Roller bearings are essential components in most mechanical systems. When they fail, it can lead to serious consequences for the machine or the products it produces. Like ball bearings, roller bearings are designed to support loads and reduce friction. Over time, these bearings may experience wear and tear, which can eventually require replacement or repair. Understanding the common causes of roller bearing damage is key to extending the life of your equipment. AdobeStock_116936499

What Are the Most Common Types of Roller Bearing Damage?

Every year, around 10 billion bearings are produced globally, with only a small percentage failing due to severe damage. Most bearings last longer than the machines they're installed in. Here are the main causes of roller bearing damage:

Common Types of Roller Bearing Damage (1)

  • Deformations: Excessive heat or mechanical stress can cause metal flow, leading to deformation in the bearing cones. This can result in misalignment of rollers and even complete lock-up.
  • Fatigue spalling: This occurs when the surface of the bearing starts to crack and flake off. It can be caused by hard inclusions in the steel or by debris that exceeds the lubrication film thickness.
  • Handling damage: Rough handling during installation or transport can cause dents, nicks, or raised edges on the bearing surfaces.
  • Cage damage: If a bearing is dropped or improperly installed, the cage can become damaged. This often leads to misalignment of rollers and potential binding during operation.
  • Preload/overload damage: Too much preload or excessive load can cause internal stress, leading to premature failure. High temperatures and lubricant breakdown can also contribute to this type of damage.

When Should You Replace Your Roller Bearing?

Determining when to replace a roller bearing can be challenging, as the time between initial damage and total failure varies. High-speed bearings may fail within seconds, while low-speed ones might take months. Early detection is crucial to avoid costly downtime and further machine damage. Regular inspections for unusual noises, vibrations, or temperature changes can help identify problems early. Addressing these issues promptly ensures that you can replace the bearing during routine maintenance, rather than waiting for a complete failure.
