Excellent quality

These bearings are incredibly smooth. Used them for a high-speed spindle project and they run cool.

Solid choice

Using for RC car upgrades. Noticeable improvement in coasting distance. One seal was slightly bent.

Good but tight fit

Quality is great but the 625 size was a very tight press fit on my shaft. Still works well.
