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 bearing to experience for any kind of skater, skateboarder or luge racer.

Bearings are gel lubricated and sealed for long lasting low maintenance.  

A quality inline micro bearing. ABEC 11 bearings are used by the serious inline 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 bearing to experience for any kind of inline skater. Bearings are gel lubricated and sealed for long lasting low maintenance.

While all bearings are extremely precise mechanisms, a designer must consider the benefits of tighter tolerances in terms of performance and bearing life. For example, there is a direct correlation with precision class and bearing life. Raceway parallelism, a feature controlled by ABEC, can impact bearing torque. A non-parallel raceway will result in torque spikes. In high speed applications, nsk bearing runout can result in an imbalance in the rotating mass. These conditions can lead to premature failure and unpredictable life. Of course, the higher precision levels have the downside of higher cost.
