Exact fit

Measured 1mm bore perfectly with my calipers. Essential for precision miniature projects.

Smooth operation

Used for my custom RC motor build. Spins incredibly smooth and handles high RPMs without heating up.

Average quality

Works but noise level varies between units. Acceptable for hobby use but not industrial.

Great for drones

High speed performance is solid. Installed them in my racing drone motors and noticed less friction.

Mostly good

One bearing had slight resistance out of the box, but the other nine were perfect. Good value for the price.
