Might need bearings in one of my axi motors. Any one know the size?

I may have damaged the bearings in a motor. 2814/22 it spins true but does not sound very good, im going to blow them out tonight but i cant seem to find any bearings, i will be buying a new motor since one is shot.
Thanks

Cancel that, a good second cleaning with air inside and out got er sorted... The smallest dust i guess can create some bad sounds.
