Amazon robotshop mecanum wheels claim to have bearing rollers but has the price of the ones that don't

these nexus mecanum wheels here claim to have bearing rollers, but they are the price of the ones that don’t on robotshop. Do they actually have bearing rollers? thanks.


I too have mistaken the New Community versus the Robot Shop itself. I am uncertain if anyone is watching this currently so as to respond to requests like this however, hope the link helps solve your need.
