Re: #25 Chain Drive Experience ???

In my experience, even #25 chain can be run fairly misaligned under some circumstances. Last year, we ran our practice bot with one sprocket on backwards. Their was not much load (it was an intake being powered), and the misalignment was fairly substantial, approximately 1/4" over about a 4" run. When we realized that it had accidentally been installed incorrectly, it had been running that way for almost a week with no problems.

I'm sure that high tension, high load drive chains are much more given to throwing with misalignment, but don't get scared away from a lighter solution. To add one more story to the others in this thread, we've run #25 drive chains for at least 4 years with absolutely no problems with misalignment. We did experience a bit of stretch, but our tensioners have solved that problem very handily.
