We added Rush bearings to the site a few weeks ago, and they have been tremendously popular. What is unique about Rush bearings, is that they are one of a growing number of companies adding an Abec9 version.

Like others, I was a little skeptical about an Abec9 rating showing up in the market. After doing some research, there is an Abec9 designation by the American Bearing Manufacturers Association. At this level of precision, the differences in speed between an Abec7 and Abec9 should be very small. The Rush Abec9 bearings are reasonably priced at $22, so they are a minor investment to see for yourself. Always remember to frequently clean and lube your bearings.
