I assume you'll be cheesholing the gears, too? I mean, if you're fretting over bearings vs. bushings, I can only think that you're planning to do that, but didn't see it in your CAD work.

Not knowing your end application, would it be reasonable to ask if a worm gear might be a suitable design. You can buy worm gears in ratios up to 80:1 off the shelf and they tend to lock in position... a handy thing if this is for an arm or lift.

Just a couple of thoughts... otherwise it looks great and you're getting some good advice on this thread!
