6.2.4.3 Linear Axis with screw drive and integrated coupling

For Linear Axis of the AXDL series is it possible to integrate the fixed bearing unit of the ball screw and the coupling in the profile. In
this case is for the drive assembly no coupling cone necessary. The drive is mounted on the Linear Axis frontally closing adapter plate.
With this version, the total length of the Linear Axis can be further reduced. The dimensions are shown in Figure 6.37 and summarized
in Table 6.28. This version can not be combined with screw drive support units.
