Review on NSK Shielded Clearance 22000Rpm Rotational by Shawn Quick

These are better quality bearings than the ones I replaced them with in my air conditioner. The AC unit was used in storage for half a season, then a full season and then in storage when I went to install it the motor was not spinning. So instead of paying $140 for a new motor, I decided to replace the bearings. (very easy if you are able to do this repair.
