I'm comparing FR5 housing-transfer tools and both suppliers justify them with the casting weight, while their fingers extend quite a way out and neither lists the adapter or fittings. The part is only one piece of what the wrist carries. What complete information would make this a purchase comparison?
Request the complete loaded assembly mass, centre of gravity and geometry, with the intended motion assessed against the applicable manufacturer limits. Include the hose fittings and how the tool approaches and releases into both nests. I mean each supplier's actual proposed assembly, not a catalogue gripper on its own
Asked both for that. One says the adapter is still to be designed, which explains the missing figures but leaves its suitability claim rather premature. I've kept the price provisional until the assembly and transfer are reviewed.
Does that supplier include the adapter design and assessment in its price? Worth establishing now, while it is still clear which work remains rather than becoming an extra after the arm is chosen
