DETROIT BEARING CO – CERAMIC PRO GRADE BEARINGS (SET OF EIGHT BEARINGS W/.50 CALIBER SPACERS)
With over a year of design and testing, Detroit Bearing Co bearings are built to our custom proprietary specifications. We feel our Ceramics out-perform “ceramic super r” brand bearings, and are as good or better than their swiss versions. Our Ceramics take speed and longevity to another level, and if you want the best, this is it.
Black silicon nitride ceramic balls (not the cheaper, softer white balls), which are about three times harder than steel, 30% lighter and won’t rust. These bearings are faster than steel, and generally last about three times longer.
Stepped inner race (both sides) creates a ledge that helps to keep dirt out, so your bearings last longer.
Extra deep ball channels help prevent bearing “sideways blowouts”, and produce a smoother ride with a more solid feel. The inner race channel is 25% deeper than the leading swiss ceramic brand.
Nylon ball retainer for light weight and low friction.
Rubber shields on both sides. Low friction, removable, and keeps dirt and dust out. And yes, dust does exist on the non-visible side, produced from the axle rubbing against the bearings! That’s why we put a shield on BOTH sides, so your bearings last longer. We never understood why some of the leading brands don’t do this.
Abec 9 rating. A high Abec rating means the bearings are built to a high production standard. Some companies use false ratings, or do not reveal their ratings, or come up with their own random rating system which means nothing. Our bearings are Abec 9, guaranteed.
.50 Caliber Spacers. A full 1/2 inch diameter (.50″), these heavy duty spacers are 16% thicker than normal, which means they won’t deform or squash, and they dissipate heat better. Made from 6061-T6 aluminum, they’re also strong, light, and will not rust. Precision machined to .410″ length (+-.002″), our spacers allow you to snug up the axle nut, reducing freeplay and wheel chatter, while still having your wheels spin properly. These spacers are the perfect high performance alternative to generic spacers or built-in spacers.
