MESYS Calculation Software

Toroidal roller bearings have an outer race radius which is larger than for a sphere. The don't have shoulders, therefore the roller can float axially.

The radius of inner race, outer race and roller can be specified as ratio to the nominal diameter of the outer race: .
The dynamic load capacity is calculated using bm=1.15 like for spherical roller bearings as this seems to be the case in catalog data of major manufacturers.
