A calculation for the load distribution and reference life L10r according ISO/TS 16281 is available online. The inner geometry can either be entered by the user or be approximated from the outer geometry. The loading is specified as force/moment or as displacement/rotation as an alternative.

In contract the the classic calculation of L10 life according to the bearing catalog the extended calculation of reference life L10r is considering the load distribution in the bearing and therefore a moment load and the operating clearance. Information about a more detailed calculationalso for other bearing types can be found here.
