Barrel roller bearing are single row spherical roller bearings. As for double row spherical roller bearings, the outer race is a sphere and the bearing does not support moment loads. Therefore, the tilting angle has to be defined instead of moment load.
The radius of inner race, outer race and roller can be specified as ratio to the nominal diameter of the outer race: . Default parameters are: fe = 0.5; fi = 0.5; fr = 0.485. If the radius for the outer race is chosen differently, the bearing cannot rotate freely any more.
The dynamic load capacity is calculated using bm=1 as this seems to be the case in catalog data of major manufacturers.
