Quiet Running

Very satisfied with the purchase. The VV seals keep the grease in and dust out. Will buy again.

Smooth Operation

These bearings are incredibly smooth. I used them for a robotics project and the noise level is practically zero. Genuine NSK quality.

Good Value

Quality is great, but shipping took a bit longer than expected. The bearings themselves work well in my drone motors.
