Bearing Life Assessment


The section's areas of expertise cover the following:
  • Analysis to determine the life expectancy of bearings putting emphasis on lubricant degradation. The analysis is based on results obtained with the Spiral Orbit Tribometer of ESTL (European Space Tribology Laboratory).
  • Analysis to determine up to what level a life test can be accelerated. This is important because life tests are very expensive and depend on the test duration which can be highly reduced if a clear assessment is done to determine accelerated tests conditions
