Bearing Pitting and Abrasion
Severe contamination and uneven wear were found on a 22228 CCK/W33 bearing, caused by inadequate sealing and grease degradation. Envelope monitoring and good lubrication practices can prevent 30% of premature failures.

Bearing Contamination Failure: Real Case with Technical Analysis
We identified a "carpet" signal in the envelope spectrum and high noise on a 22228 CCK/W33 bearing. After disassembly, we confirmed severe contamination on the inner track with uneven wear (pitting and abrasion).
📌 Root Cause:
- Ingress of abrasive particles (putty/fibers) due to inadequate sealing.
- Degradation of grease by contamination.
💡 Lessons: Envelope monitoring + good lubrication practices prevent 30% of premature failures!
