Perfect for my drone build

These bearings fit perfectly into my motor mounts. The rotation is smooth and there is no noticeable play. Great value for the price.

Good quality, slight variance

Overall very happy with the purchase. One bearing out of the ten was slightly tighter than the others, but still usable for my project.

Okay but packaging weak

The bearings themselves are fine, but the plastic bag they came in was torn upon arrival. Luckily none were lost, but better packaging is needed.

Great for 3D printers

Upgraded my extruder assembly with the 5mm inner diameter set. Significant improvement in filament feed consistency. Highly recommend.

Excellent precision

Used these for a high-speed spindle application. They run cool and quiet. The stainless steel ensures they won't rust in my workshop environment.
