Factors influencing bearing vibration level

This article presents the problem of factors influencing bearing vibration level, which is a comprehensive parameter providing information about bearing condition. Basing on technical literature and research experience, factors affecting bearing vibration level will be defined, both originating from shape errors, as well as those that may have occurred during long-term operation. Additionally, the methodology is described in accordance with ISO-15242 standard, concerning bearing vibration level tests performance. Experiment considered bearing vibration level measurements for bearing 6208C3, for post-production parts and those that have passed durability test. Comparative analysis included a compilation of numerical values and finding a correlation between level of bearing wear and mentioned parameter.
