Got all 20, feels smooth
Have not used them long term or anything. Just an initial review. My use case is light though, not many rpms/load.

Tolerances
Not really impressed by these bearings, the tolerances seem to be loose..i find the inner race wobbly and these bearings are “rough”. I Replaced my original motor bearings that were damaged/rough with these and they sound even worse. The installation was done properly
