Explanation to table

A bending moment, created by radial forces, results in an additional load for the Locking Assembly, shaft and hub. This load creates an additional pressure, works in rotation and has to be superpositioned with the pressure resulting from the Locking Assembly. For a viable connection, a minimum surface pressure at the contact areas between Locking Assembly, shaft and hub must be maintained, as soon as shaft and hub have to take up the maximal pressures. Additionally, the listed torque values (T) have been reduced due to the additional bending moments. To achieve lower stresses for the Locking Assemblies the screw tightening torques (T_A) have also been reduced.
