Very good bearings but useless without the etching identification information. Management need to train employees to know that this etching information on their bearings should be on them as it seems most are unaware if it's a requirement or not!
Svantaggi
NTN doesn't even know if their bearings should have the identification etching around the outside of the ball race lol.
Bearings are going out completely blank and to anyone that didn't know any better they could just be fakes!
