■The maximum loads refer to<br />
50 Hz. Please inquire about<br />
60 Hz operation.<br />
The figures for the maximum axial<br />
loads have been calculated<br />
assuming that standard coupling<br />
types are used for the<br />
drive. For suppliers, see catalogue<br />
section "Accessories and<br />
Repair parts".<br />
Please enquire about 1MJ8 and<br />
1MJ1 motors.<br />
Please ask for advice if the loading<br />
direction alternates.
