Hex Shaft Wear Experiences

[sanddrag]

With 7075 hex shafts, and 6061 wheels with about 5/8" maybe length-through-bore, we've experienced no wear issues. The key is to make sure your broached hole and hex shaft are a rather close fit. I've noticed some of the AndyMark ones are a little loose, but I would not be concerned about them rounding out.

I believe some of the issues that occur with the Toughbox and other mass produced hex shaft mechanisms, is the fact that they are mass produced. There is a tolerance in which the parts are made, some will be further from perfect then others.

We used live axles with cantelevered wheels last year using 1/2" hex aluminum. It worked out very well. The wheels were AMs with hex bore and some omni's with the hex adapter. The sprockets on the wheel axles were nylon and the problems we had with wear was on the sprocket teeth due to inadequate tension in the chain. We had no wear in the hex parts at all.
