NOTE
1 When using a belt, adjust the tension so the
allowable loads indicated above are not exceeded.
If an excessive load is applied, consider the use of
a support bearing on the machine side to maintain
the long-term reliability of the motor. (If an
excessive load is applied, it is possible that an
abnormal sound may occur.)
2 When the belt tension is maximized at a point
outside the output shaft end, the allowable loads
are less than those at the output shaft end.
3 If a thrust load is applied when a helical gear is
used, the shaft moves in the direction of the thrust.
So, as a general rule, never apply a thrust load.
