I don't think you'll be happy with the ceramic bearings...they are mostly intended for electric motors and they are not as shock resistant as steel. Also.. There is not a practical rolling resistance issue with the stock steel bearings, so no need IMO to go with extra expense ceramic hybrids.
The bearing on the clutch side (PTO), jack and drive shafts, Polaris Part number 3514617 (is a spherical outer race (the outer race is rounded on the OD) ... not usually stocked and not common. CS205LU... I'd go with a factory Polaris bearing for that.
That bearing measures 25mm(ID) x 52mm(OD) x 15mm(thick)
The 6205 bearings, Polaris #3514308, on the Quick Drive bearing plate top and bottom are double sealed and greased with cold-weather-compatible grease....(6205-2RS)... I'd go with the stock replacement. That bearing measures 25mm(ID) x 52mm(OD) x 15mm(thick) as well.
Polaris bearings, for a while now, are NTN Japan bearings and high quality.
The 6205 bearings are common. the CS205LU's are not, and I highly doubt you'll find a ceramic-hybrid sub for the CS205LU.
