Bearing Wear at Industrial Fan Motor
Vibration analysis of an industrial fan motor identified wear in the LOA bearing, indicating imminent failure. Preventive maintenance, including bearing replacement, avoided catastrophic failure and ensured operational continuity.
Vibration collection was performed in an industrial fan motor, where a significant increase in amplitude was observed, reaching 6.5gE, a value that fits the ALERT condition, according to the previously established parameters.
📊 After analyzing the vibration spectra, wear was identified in the engine's LOA bearing, with emphasis on the characteristic frequency of failure in the internal raceway (BPFI) and external raceway (BPFO) — a strong indication of imminent failure.
🛠️ Based on this evidence, a planned corrective intervention was carried out, following the recommendation of the predictive maintenance team. After the bearing was replaced, a detailed inspection was carried out, which confirmed the loss of material and severe wear, validating the diagnosis made via vibration analysis.
✅ Preventive action was essential to avoid a possible catastrophic failure of the equipment, ensuring operational continuity and reinforcing the importance of predictive maintenance techniques.
