What is it about?

Open access article. The main goal of this research results was to establish statistically significant correlation between several variables: rolling bearings surface temperatures, radial vibration intensities, service life and concentration level of debris particles in bearing grease.

Why is it important?

At this moment, developed experimental methodology is applied only to open pit coal mine conveyor idler’s rolling bearings, but its principles are universal, so with minor modifications it could be used for prediction of any of listed variables for different kinds of rolling bearings, operating in different environments.


Taking into account total number of tested bearing samples it could not be fully claimed that developed mathematical model is perfect – however, at the moment it is unique, so it could be successfully used as a basis for further researches. Finally, developed testing methodology could be used for qualitative assessment of different types of rolling bearings, indirectly increasing the overall quality of matching conveyor idlers and other rotating machines
