Yes,Dan,they are class 7!!! You can buy up to class 5 for roller skates. I'd still want at least class 7. My Hardinge HLVH has class 9,but I don't think that is really necessary for a decent spindle.
A while back I wanted to built a super accurate high speed spindle,which I never got around to,and bought some bearings from surplus for $200.00. I could be wrong,but I think they are good for 350,000 RPM(It's been several years). They retailed for much more than I paid.
