Bearing #1Thermal Scan

Pillow Block Bearing

Overheating from friction due to degraded or insufficient lubrication. If left unresolved, may lead to premature bearing failure or seizure.

Surface temperature exceeds normal operational limits for this bearing class. No visible external damage or deformation. No known noise, vibration, or performance symptoms reported (image-only evaluation).

The image reveals a clear thermal anomaly at the center of the bearing housing, peaking at 144°F (62.2°C). The localized hotspot contrasts against the cooler surrounding areas, indicating concentrated friction or insufficient lubrication.

Use ultrasonic or vibration analysis to check for internal damage. Visually inspect lubricant condition and quantity. Check for signs of alignment issues (e.g., uneven wear, excessive axial load). Compare to a baseline image under similar load conditions.

Re-lubricate bearing with correct grease grade. Schedule follow-up thermal scan in 7–14 days. Evaluate alignment and shaft tension. Consider condition-based maintenance strategy with thermal and acoustic trending.
