Hello- We are using this gripper to grip on the I.D. of a steel part and noticed if we get too far out towards the end of the gripper finger we see a buckling of the linkage, and drop the part. The data sheet I have for the gripper shows an image of it being used in this fashion but the specs do not mention any capacities or limitation of using it this way versus griping externally. Are there any limitations? Is there something we are doing wrong? Thanks in advance for your help.

If I understand correctly you are picking the parts over the "equilibrium" line where the Gripper will switch from parallel grip to encompassing grip. Can you do a short video with your cell phone to show me the issue ? The latest 2-Finger 85 can be locked in parallel mode so that you could avoid this. Best,

See attached. Hope audio quality is ok. Thanks

That's perfect, it's what I thought. You should put in the "parallel locking" pins in that hole you were pointing. It's a 5 mm diameter h6 shaft if you want to do your own. We sell them with snap ring slots and you can mount them just like the other axes on the Gripper. If you want to order them from Robotiq you will need part AGC-PARA-KIT-002 at 40$, you will need two of them.

Thanks very much for the help. We bought the pin kit and everything is fine.
