Perfect fit for my RC car

These bearings are incredibly smooth. I used them for my competition RC car and noticed less friction immediately. Genuine KIF quality.

High quality precision

Exactly as described. The P5 precision is noticeable compared to standard bearings. Will buy again for my drone builds.

Fast delivery and well packaged

Arrived quickly and each bearing was individually wrapped to prevent damage. No noise during operation at high speeds.

Genuine product verified

I was worried about fakes but these have the correct KIF markings. Spin time is excellent. Highly recommended for robotics.

Good value overall

Most of the bearings were perfect. One had a slightly tight shield but still usable. Good price for Japanese imports.
