Banggood

As expected and described

Broke my bearings and replaced it with these. Smooth straight out of the bag and tolerance is very acceptable. Very happy and my quad has virtually no vibrations.

I bought a couple of bearings to keep them handy as I am running EMAX RS2205-2300KV (Red Bottoms) on 2 quads - a ZMR250 and a QAV210. If you hear the motors make a crunching-like noise, most likely it is the bearing that needs to be replaced. These bearings are definitely a must-have spare as they are good quality and very smooth - no vibrations at all and can save you a crash if the bearing fails. Definitely recommended!

These bearings fit well to racerstar BR2205 2600KV. To do the replacement, I used these tools of mine (photos), they are very easy to use: 5 minutes per bearing, directly on the drone! No more vibrations...

Looks good not tested yet.

My Emax Red Bottom motors have been a true pleasure to own. They have been very fast, reliable and worth every penny I've got invested in them. One of my prized motors began to develop a little grinding noise and I immediately ordered a few replacement bearings from Banggood. They have injected new life into my beloved motors. They are now ready for a few more hours of service. Great quality, great price and quick delivery. Plus, plus, plus!!

We can use this if the dimensions of bearings are 3x4x8

Good bearings. I've read on RC groups these can also be used on the Eachine x220s 2206 motors. So I've orderd a couple so I can replace them when the bearings go bad. (1 motor is already not souding entirely smooth anymore)

Крутятся мягко. В смазке. доехали быстро. Рекомендую. В двигатель ещё не ставил но визуально хороши

Отличное качество подшипников.
