Note
The permissible axial force is absorbed exclusively by the deep-groove ball bearing of the duplex
bearing. The cylindrical roller bearing absorbs the radial force. The axial force F

that is
permissible during operation is calculated as stated in table "Calculating the permissible axial
force (Page113)."
