Scoring

Services - Troubleshooting - Damage by Type - Scoring is surface damage due to accumulated small seizures caused by sliding under improper lubrication or severe operating conditions. Linear damage appears circumferentially on the raceway and roller surfaces.

Seizure

Services - Troubleshooting - Damage by Type - Seizure: When sudden overheating occurs during rotation, the bearing becomes discolored. Then, the raceway rings, rolling elements and cage will soften, melt and deform as damage accumulates.

Rust and Corrosion

Services - Troubleshooting - Damage by Type: Bearing rust and corrosion are pits on the surface of rings and rolling elements and may occur at the rolling element pitch on the rings or over the entire bearing surfaces.

Smearing

Services - Troubleshooting - Damage by Type - Smearing is surface damage which occurs from a collection of small seizures between bearing components caused by oil film rupture and/or sliding. Surface roughening occurs along with melting.

Cage Damage

Services - Troubleshooting - Damage by Type - Cage damage includes: Cage deformation, fracture and wear; Fracture of cage pillars; Deformation of side face; Wear of pocket surface; and Wear of guide surface.

Cracks

Services - Troubleshooting - Damage by Type: Cracks in the raceway ring and rolling elements. Continued use under this condition leads to larger Cracks or Fractures.
