24" X 1" Belt Grinder

[DIYSwede]

Quick question: -Anybody having problems overrevving ball bearings?

For instance, given the 12 000 rpm angle grinder and a 60 mm OD drive wheel,
the suggested 62200 2RS1 (with 17000 max rpm) would get up to 24 k rpm...

(A 43 mm OD drive wheel would keep the revs down, but still provide 60 mph belt speed)

Any risk and/ or damage assessments out there?

Just asking, and better safe than sorry...

Yes. You are right. Thanks for pointing this out.
It's better to put 3 bearings 6200 2Z (limiting speed 24000 rpm) than 2 bearings 62200 2RS1.
When I was ordering bearings, I ordered 6 pcs 62200 2 RS1 and 9 pcs 6200 2Z, but decided to keep these 6200 2Z for some other projects.
Will replace them once I come back home.
