this bearing is a perfect fit for the brushless motors used in the BLADE 200 SRX. Soak them in scorpion bearing oil and they run as smooth as silk.

Bought these to replace noisy bearings in an outrunner motor. New bearings were noisier and looser than the old worn out ones. I think these may be too inexpensive to be useful.

Great price on one of the most common bearings used in motors with 3mm shafts. I always keep some around for rejuvinating motors that are wearing out the original bearings. At 13g shipping weight you can use them to max out the weight on an order before bumping up to the next weight bracket.
