Smooth operation
Replaced an old noisy bearing with this one. The difference is night and day. Very quiet and runs cool under load.

High quality bearing
Used for a skateboard wheel project. The P5 precision grade makes a noticeable difference in noise reduction. Very satisfied.

Genuine part, perfect fit
Ordered this for my electric motor repair. Dimensions are exact and the rotation is incredibly smooth. Definitely genuine NSK quality.

Good but packaging loose
The bearing itself is excellent and works as expected. However, the packaging was a bit loose during shipping. Product arrived safe though.

Fast shipping
Needed this urgently for a machine repair. Arrived faster than expected and fits the 17mm shaft perfectly. Would buy again.
Q: Is this made in Japan or China?
A: This specific SKU is imported from Japan, as indicated in the product title and specifications.
Q: Is this bearing pre-lubricated?
