Precision ball bearings in tolerance grades ABEC-5 and ABEC-11 are recommended for applications where high speed and/or extreme running accuracy is required.

These bearings have the same nominal external dimensions as equivalent size ABEC-1 grade bearings; however, the running characteristics and external dimensions are held to closer tolerances.

Bearings have a couple of measurements that you should be aware of. 8mm, shown with these bearings, tells you the diameter of the inner hole. This diameter matches the diameter of the axle used on the trucks. 8mm axles are by far the most common.

The next number is shown as an abec rating. This number classifies the precision of a bearing when manufactured. [abec 11 bearings] is considered the lowest rating, and abec9 as the highest. An abec9 bearing will be ground or polished to a higher tolerance and in turn may be faster and last longer. A very precise bearing will have reduced friction, friction causes heat, and heat ultimately will cause bearings to fail.

We always recommend that you clean and lube bearings regularly. A well maintained Abec5 bearing will outlast an Abec11 bearings that is not maintained.An inline rollerblade, skateboard or luge racer's bearing. ABEC 11 bearings are used by the serious skater who wants the best. The manufacturing of this bearing is difficult and costly. The tolerances are very tight and they have virtually no friction under the load of your weight. They are truly a nice nsk bearing to experience for any kind of skater, skateboarder or luge racer.

A racer's bearing. ABEC 11 bearings are used by the serious inline rollerblade skater or skateboarder who wants the best. The manufacturing of this bearing is difficult and costly. The tolerances are very tight and they have virtually no friction under the load of your weight. They are truly a nice bearing to experience for any kind of skater or skateboarder. Bearings are gel lubricated and sealed for long lasting low maintenance.

The ultimate bearing for inline rollerblade, skateboard or luge racers. Solid Silicon Nitride ceramic roller balls. Ceramic ABEC 11 bearings are used by the serious inline rollerblade skater, skateboarder or luge racer who wants the best.  Bearings are oil lubricated and sealed for long lasting low maintenance.

A quality quad skate bearing. ABEC 11 bearings are used by the serious quad skater who want the best. The manufacturing of this bearing is difficult and costly. The tolerances are very tight and they have virtually no friction under the load of your weight. They are truly a nice ntn bearing to experience for any kind of quad skater. Bearings are gel lubricated and sealed for long lasting low maintenance.
