Great quality seals
I ordered the 2RS version for my 3D printer fan motors. They keep dust out effectively and run quietly.

Exactly as described
Dimensions matched the spec sheet perfectly. I used the MF128 model for a small robotics project. Very satisfied.

Perfect for RC Car Upgrade
These bearings fit perfectly in my wheel hubs. The flange helps keep them aligned properly. Smooth rotation right out of the box.

Good value but tight fit
The bearings are high quality, but the fit was slightly tight in my housing. Needed a gentle press to install. Works great now.
