High quality stainless steel
Using these for a small conveyor mechanism. They handle the load well and haven't shown signs of rust.

Perfect for custom builds
These bearings fit perfectly in my FPV drone motors. Smooth rotation and no noticeable play.

Solid basic bearings
Good for general miniature applications. Not industrial grade but perfect for hobbyist use and prototypes.

Smooth operation
Replaced the old bearings in my RC car motor. Much quieter and spins longer than the previous set.
