Note 1 The graphs show the values for allowable load and allowable moment in static on one finger.
Note 2 The values for the allowable moment are those when the load is applied in one direction
only.
•
The values become one half when the load is applied from in two directions.
•
The values become 1/3 when the load is applied from in three directions.

Refer to “1.2.2 Relation between Current Limit Value and Grip Force” for gripping force F
G
.
As the grippuing force is a reference value, it is multiplied by 1.5 for the safety margin in the moment
calculation.
