This is half a spherical roller bearing with only a single row. It can be used to assemble asymmetric spherical roller bearings using the shaft calculation.
Like for spherical roller bearings 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 tilt freely anymore.
The Distance to row center defined the axial position of the roller. It should be defined to that the center of curvature is on one side of the bearing. The distance to the center of pressure 'a' should be equal to the bearing width.
