The Roll-Line Speed Race Bearings are specifically made for very High Level Competitive Roller Skating.
The Speed Race Bearings are Free Rolling with minimal Radial Play which promotes and very evenly distributes the load across the 7 balls
for optimal Roll and a 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.
These provisions in the Race Curvature and Contact Angle allow the Roll-Line Speed Race Bearings to Roll very freely.
The Roll-Line Speed Race Bearings have a single rubber Shield to help keep the dust and dirt out.
The high performance Ball Crown Cage is Carbon impregnated to provide a little extra dry lubrication to ensure these Bearings
will perform far beyond most other Bearings.
Roll-Line Speed Race Bearings with the Yellow Shield come ONLY in 7mm, make sure to check your truck for the 7mm Axles.
These ultra high performance Roll-Line Speed Race Bearings will perform at the level of some of the most expensive ceramic bearings,
but have the resiliency and strength to provide better performance for much less cost.
The Roll-Line Speed Race Bearings are skated on by most of the World level Skaters and Champions in Artistic and Quad Ball Hockey.
