1 Intended use
If the gripper finger has some clearance, if the positioning is incorrect or if
movement is asymmetrical, the gripper finger will need to be changed. Ex-
pansion cracks or enlargement of the guide groove are the most frequent
indicators of a defective gripper finger. The cause for this defect is often a
collision. After a collision, the piston rod may also be damaged.
