The limit values shown for the bearing load refer to equivalent forces to be determined mathematically, whose effect is equivalent to the forces occurring in the load profile. They only apply to radial and axial loads. Axial forces up to maximum FA = 0.24 × FR are permissible in case of superimposition. They apply to the output speed of 100 rpm and in case of radial force for a force application point in the center of the shaft or for centrally applied axial force. For other speeds or force application points, the permissible radial forces must be obtained from the radial force diagrams of the Configuration Manual.
