I know for a fact that each of the crab drive modules on our robot this year had a snap ring (about 1/2" diameter I think, but don't quote me) holding them to the shafts that essentially bore the weight of the entire robot, which i would think would fall around 25 lbs per snap ring or so when you consider that they don't bear the weight of the wheels themselves and then the battery is added. So if you are concerned about their durability when bearing force, I would think it shouldn't be a concern. The only times I know of this season when we broke or warped a snap ring was when we were taking them off or putting them back on. They were very reliable for our application, but I can't say much about their application in live axle design.
