طبقه‌بندی کننده آسیب یاتاقان

ISO 15243 classifies rolling bearing damage into six main categories: fatigue, wear, corrosion, electrical erosion, plastic deformation, and cracking/fracture.

Fatigue spalling is the expected end-of-life failure. Premature failures are most often caused by contamination, inadequate lubrication, and improper mounting.

Fatigue shows material flaking in the loaded zone (develops over time). Brinelling shows permanent indentations matching rolling element spacing (single overload event).

Stray currents from VFD-driven motors cause characteristic fluting patterns. Use insulated bearings or shaft grounding rings to prevent it.

Proper lubrication, contamination control, correct mounting, alignment, and vibration monitoring are the key prevention measures.
