The Roll-Line Speed Race ABEC 9 bearings are wonderfully free rolling with the absolute minimal radial play which promotes and very evenly distributes the load across the 8 balls for optimal roll and a very good amount of axial play or thrust, which is the side movement of the inner race in relation to the outer race. This movement is very important because when skaters push, we always put side load on the skate to get power in the push or stroke. If the bearing does not allow for this, it will bind and loose operating speed or roll. The Speed Race Bearing is made with a special kind of steal and is very resistance to deformation and is closed and therefore resistant for dirt and stick on the court.
