Calculation of a deep groove ball bearing

The pressure distribution and the reference life L10r of a deep groove ball bearing is calculated according to ISO/TS 16281. The loads are applied to the inner ring and the displacements are shown for the inner ring relative to the outer ring. A demo version for windows is available here.
These online calculations are provided free of charge by MESYS AG. The software is tested and no errors are known, but there is no warranty for the correctness of the results and for the availability of the calculations. The usage is at own risk.
