Bearing Analysis: Flaking
Condition
Raceway surface is flaked. Surface after flaking is very rough
Cause
Rolling fatigue. Flaking may be caused early by over-load, excessive load due to improper handling, poor shaft or housing accuracy, installation error, ingress of foreign objects, rusting, etc.
Solution
- Find the cause of the heavy load
- Examine operating conditions and adopt bearings with larger capacity as necessary
- Increase viscosity of oil and improve lubrication system to form an adequate lubricating oil film
- Eliminate installation errors
