Perfect for drone motors
These bearings fit perfectly into my motor housings. The flange keeps them secure without extra clips.

Solid construction
Heavy duty feel. The rubber seals seem durable against dust. Would recommend for machinery.

Good quality overall
Smooth rotation and well packaged. One bearing felt slightly stiffer than the others but loosened up after use.

Excellent precision
Used for a robotics arm project. The stepped shoulder aligns perfectly with the shaft design.
