Smooth Operation
Very quiet running bearings. I used the 6203 LLU for a fan application and the rubber seal keeps dust out effectively. Highly recommend.

Genuine Parts
Bought the 6205 ZZ for my motor repair. The packaging was original and the bearing runs smoothly without any noise. Definitely genuine NTN quality.

Good Value
Quality is great and fits perfectly. Only giving 4 stars because shipping took a bit longer than expected, but the product itself is flawless.
