Re: Introducing Revolution Pro...crab/swerve module

Thank you so much for this, I took a cross section and noticed there is a 1/2"id bearing right above the vertical bevel gear that doesn't seem to be doing anything. If it were 3/8 it would be guiding the shaft which would make sense, am I missing something? I also noticed there are no thrust bearings anywere, only thrust bushings, I guess you have found this to be acceptable?
Looks like a modeling typo. It's the same 3/8" ID bearing shown at the top of the stack. Thrust bushings are the answer. We used them on the classic Revolution and they performed great. Actually a lot of swerve guys think you can send the thrust loads directly into the ID of the bearing....I like the additional overhead that the bushing provides.

Also, in the prototype with the hex shaft sticking out the top how did you manage to assemble that without using larger diameter hex bearings and thus a larger overall diameter?
The shaft was 1/2" hex to 1/2" round to 3/8" hex. It used a 1/2" ID x 7/8" OD bearing....the same one incorrectly shown in the model actually. Vexpro sells them. We changed back to the keyed shaft as the original design was cost prohibitive.

I've updated the model with the correct bearing.
