High quality miniature bearings
Used these for a small conveyor project. Precision is spot on for the price point.

Perfect for my drone motors
These bearings fit perfectly in my 2205 motors. Very smooth rotation and low noise.

Reliable for electronics cooling
Replaced fans in several units. These bearings handle the RPM well without overheating.
