No I haven't reached out to vex however I still believe they should put the bearing specs on their website. And I don't believe that the bearings specs are in excess for every single frc application. I believe that their max rpm is a lot lower than everyone "assumes". I will reach out to vex about their bearing specs. But 1000 rpm difference with only a bearing swap is very significant in my eyes.

Sorry, were you using half inch round Vex bearings and then switched to half-inch round McMaster bearings? If so, then I'll agree that the McMaster bearings were an improvement over the Vex.
If you're talking about switching from half-inch HEX bearings to half-inch ROUND bearings, then that's a whole different ballgame. Vex notes in a few places that hex shaft in hex bearings can have some tolerance issues, and I would expect them to have some minor issues running at higher speeds. So apples to pineapples.
