Bearing is an essential component in a mechanical rotating equipment system. It is no less important than lubrication to prevent wear, which is very important to consider in the mechanical maintenance system of rotating equipment. Bearing wear is one of the problems in wind turbines that will increase maintenance costs, shorten the turbines lifespan, and cause component or overall damage to the wind turbine. The latest technology has provided instruments for analyzing the damage of elements in a bearing according to the caused vibrations. Therefore, this study was performed on Ball Bearing Turbine Propeller to identify the dynamic characteristics of Ball Bearing with and without lubrication. The test was carried out using the Bump Test method applied in three measured parts: X, Y, and Z axes. The measuring instrument which was used was Fast Fourier Transform (FFT) Analyzer (Ono Sokki) and the data were analyzed using MATLAB. It was identified that the application of oil could reduce the amplitude and decrease the frequency. Personal frequency appearing more than once indicates the existence of global vibration modes. The frequency which only appears once in the measurement spot indicates local vibration modes. The highest frequency both after and before the application of oil was found in the Y-axis.

The study concludes that personal frequencies consistently appear in both scenarios, with and without oil application, at 4 Hz and 12 Hz, indicating the presence of global vibration modes.The addition of lubricant effectively reduces vibration amplitude at the same frequencies across all measured axes.Furthermore, the Y-axis consistently exhibits the highest frequency both before and after oil application.

Penelitian lebih lanjut dapat dilakukan untuk menginvestigasi pengaruh berbagai jenis pelumas terhadap karakteristik dinamis bantalan bola, dengan mempertimbangkan viskositas dan komposisi kimia pelumas sebagai variabel penelitian. Selain itu, studi komprehensif mengenai dampak kondisi lingkungan seperti suhu dan kelembaban terhadap kinerja bantalan bola pada turbin angin perlu dilakukan untuk memahami degradasi bantalan secara lebih mendalam. Terakhir, pengembangan model prediktif berbasis data yang menggabungkan hasil pengujian bump test dengan data operasional turbin angin dapat membantu dalam memprediksi kegagalan bantalan secara proaktif dan mengoptimalkan jadwal perawatan, sehingga meningkatkan keandalan dan efisiensi turbin angin secara keseluruhan. Penelitian-penelitian ini diharapkan dapat memberikan wawasan yang lebih baik tentang perilaku bantalan bola dalam aplikasi turbin angin dan berkontribusi pada pengembangan strategi perawatan yang lebih efektif.
