Most customers know when there is a bearing problem. It’s usually identified by rising bearing temperatures, bearing noise and bearing seizure. The bearing is quickly replaced to reduce downtime, and all is well . . . until it fails again. A failure analysis of the bearing will often result in finding the root cause for the failure. The customer can then schedule the required corrective actions to eliminate the problem. Some common failure modes include:

Fretting Corrosion Relative movement between bearing rings and shaft and housing Check and correct shaft and housing fits
Debris Denting Ingress of contamination that is trapped under rolling elements Improve seals; check for contaminated lubrication
Peeling Inadequate lubrication film allows metal to metal contact Check for lack of lubrication; check lubrication viscosity
Brinelling Raceway denting caused by impact often at installation Use proper installation tools including a bearing heater
Smearing Rolling elements slip in rolling motion due to inadequate lubrication Check for lack of lubrication; check lubrication viscosity

These are just a few. There are several other conditions also found in failure analysis. OTP can help. We have the experience and expertise on hand to conduct a thorough bearing failure analysis, and we can often do this at our customer’s location. At OTP, we work very closely with our manufacturing partners, who can assist when a more extensive laboratory analysis is required.
