I recently purchased 30 bearings to upgrade my workshop equipment and I`m pleased with the FGen 608 2Rs Bearing Steel .Thanks to my knowledge gained in practice, I can confidently say these bearings are high quality and perform smoothly with low noise for all my projects. The bearings are durable and will not corrode easily despite being used in various conditions. The only downside is that they were a bit pricey compared to other options in the market. Overall, I highly recommend these bearings for any industrial and scientific applications..
