As I had already changed to a bigger motor [...]
Can you link to what motor did you use? Thanks.
Was just a cheap 56C inverter rated motor I found on eBay used. I didn’t seek out a specific motor model.

I am planning to upgrade to a 2HP 3-phase motor plus a VFD, and would like to know what bearing sizes does one need to replace the stock ones?

The exploded view in the manual on the precision Matthews website has all the bearing part numbers listed.

I don’t remember them all. I’d reference that. Make sure you order high quality bearings.
