In the modern industrial system, high - speed bearings, as core mechanical components, are widely used in many fields such as aerospace, automotive manufacturing, and precision machine tools. Their stable operation plays a decisive role in the overall performance of the equipment. This study precisely focuses on the vibration characteristics of high - speed bearings under different lubrication conditions. By building a high - precision experimental platform and using advanced sensors and data analysis techniques, it deeply analyzes the influence mechanism of lubrication conditions on vibration characteristics. The research clearly shows that reasonable lubrication can significantly reduce the vibration amplitude and effectively reduce potential failure risks. Conversely, improper lubrication can easily lead to serious mechanical failures. The research results provide a solid theoretical basis and strong technical support for the optimized design and efficient maintenance of high - speed bearings, and are of great value in practical engineering applications.
