I’m no bearings expert but my gut tells me that if I were to start making cheap toys for kids that centered around bearings that had no significant durability or precision requirements, I would probably not opt for a bearing design that was rare or expensive or unique.

In fact, I’d probably go knocking on doors of those companies that do have strict requirements and be like, gimme all the ones that failed inspection.

In fact #2, if i wanted to retire and make everyone in Lemmy threads like this one jealous, I’d start thinking about what other high precision parts probably get thrown out if they fail inspection, that I could buy for next to nothing, and how I could make that into a toy.

Parts of machines are cool. Parts of machines that are crafted to high standards of precision are cool. The toy probably invents itself. Going viral and getting as popular as fidget spinners tho… That seems harder.
