The recommended minimum gripping force is 25% of the nominal gripping force. If you need 

to grip your workpiece with a lower gripping force, please run suitable tests with your applica-

tion-specific fingers mounted. Keep batch variations in mind. If in doubt, discuss your applica-

tion with our technical support team.
