Conveyor Belt Pulley Bearing Fault
Vibration and temperature measurements on conveyor belt pulleys revealed an incipient failure frequency on the outer race of the cylinder head pulley bearing. It is recommended to replace the bearing on both sides.
Condition/Development
Vibration and temperature measurements were taken on the cylinder head, on the hydro-draining side, of conveyor belts #1 and #2 to determine their condition.
Results obtained:
• According to the measurements taken, the cylinder head pulley bearing on the hydro-draining side shows an incipient failure frequency (BPFO) on the outer race, with multiple harmonics (see spectrum and circular waveform).
• Reflected temperature: 43°C - Similar bearing: 41°C.
Recommendation: It is recommended to replace the bearing on both sides.
