Permissible input torque

If you use a motor that exceeds the permissible input torque, consider taking a necessary
measure such as limiting the motor torque.
Model number Permissible input torque [N·m]
KRF3 0.154
KRF4 0.355
KRF5 0.671
KRF6 1.035

Static permissible moment

Static permissible moment is shown in Table 10. For the direction of the moment, see Fig. 6.
(The static moment is the value when a load is applied only to one direction. )

Table 10 Static permissible moment
Note) The static permissible moment is the value when all of the mounting holes of the table are
used.
Note) The static permissible moment is the maximum moment permissible under the static
condition.
