<![CDATA[Three-phase induction blower motors are important components in industrial operations; therefore, appropriate maintenance is required to maintain their reliability and performance. This study aims to analyze the condition of the BC602 blower motor at PT MFI based on vibration and temperature measurements before and after bearing replacement as part of a predictive maintenance approach. Vibration measurements were conducted at six points: the Drive End (DE) and Non-Drive End (NDE), each measured in the vertical, horizontal, and axial directions. The results showed that vibration values before bearing replacement ranged from 8.48 to 9.83 mm/s, whereas after replacement, they decreased to 0.31–1.06 mm/s. At the DE, the temperature decreased from 65°C to 49°C, while at the NDE, it decreased from 58°C to 45°C. These results indicate reductions in vibration and temperature following bearing replacement. The observed changes suggest that the maintenance action contributed to improving the operating condition of the BC602 blower motor. Periodic vibration and temperature measurements can serve as a basis for equipment condition monitoring, helping identify potential abnormalities and supporting maintenance planning.]]>
