Re: VEX pro bearings tolerances
In light gauge sheet metal for a press fit the Mfg engineer can make the hole a D shaped hole. The engineer adds a small .001 flat in to help keep the part retained. The Design engineer should draw the hole to the size of the bearing.
Annotate the CTF drawing that the hole is a press fit bearing hole.
Better to be under than over in size when it comes off the machine. Always consider heat, vibration, load, bearing length, etc in the design to retain the bearing.
