Smooth rotation and durable

I use these for small electric motors in my workshop. They run quietly and handle high RPMs without heating up too much. Will definitely order again.

Great value for imported bearings

Hard to find genuine imported miniature bearings at this price point. They work great for my RC car upgrades. No play or wobble detected.

Good quality but shipping took time

The bearings themselves are excellent quality and match the specifications provided. Only reason for 4 stars is the shipping took a bit longer than expected.

Perfect fit for my drone motors

These bearings are exactly what I needed for my custom drone build. The R6 size fit perfectly and the rotation is incredibly smooth. High quality German engineering shows.
