Three Main Causes of Bearing Failures

There are many reasons that can cause bearings to fail, but we will focus on the top three main issues.

  1. Improper Installation: Using the wrong installation method can result in bearing failure. When installing a bearing make sure that the tools used are not causing damage to the bearing. A proper bearing installation method such as a fitting tool or an induction heater to mount the bearing without additional damage will decrease the chance of damage during the install.
  2. Severe Operating Conditions: When your bearing is exposed to extreme conditions such as overloading the bearing, excessive shock loads, or extreme vibration can lead to failure in the future. When an application is creating excessive speed that are too much for the bearing, the bearing can also fail. Conditions like these should be monitored to avoid damage.
  3. Lubrication Issues: Too much or too little lubrication creates environments that lead to bearing damage. Choosing the wrong lubricant for the application is an additional factor. Always refer to your manufacturer’s specification for the correct lubricant as well as the amount and frequency of lubrication.

To prevent your bearings from premature failures, make considerations for the issues above. There are other variables that can contribute to bearing failure, but these are some of the most frequent ones.
