Cylindrical roller bearings whose inner and outer rings comprise either a rib or loose rib can accommodate a certain magnitude of axial load, as well as radial load.
Axial loads allowable for cylindrical roller bearings can be calculated using the following equation.
Fap =9.8 fa fb fp dm2 where:   Fap : maximum allowable axial load   N   fa : loading condition factor Table3-3   fb : bearing diameter series factor Table3-4   fp : rib surface factor Fig.3-1   dm :   mean diameter of bearing bore d and outside diameter D   dm = (d+D)/2       mm
