Direct connection to the spindle
NOTE
1 When using a belt, adjust the tension of the belt so
that the allowable value listed above is not
exceeded.
If the machine tool is to run with the allowable value
exceeded, examine use of support bearings in the
machine tool so that its reliability can be maintained
for a long time. (If the allowable value is exceeded, it
is likely that noise may have occurred.)
2 When the belt tension center is positioned beyond
the end of an output axis, the allowable load
becomes smaller than that at the end of the output
axis.
3 If a load in the thrust direction is put on a helical
gear, the shaft shifts in the thrust direction. As a
rule, therefore, avoid such a load on the helical
gear.

directly to spindles.
