Nylon Spacers .285 for use and fit between the bearings on the axle inside the wheel between your 8mm bearings to insure a precision fit.
Bearing spacers are small cylinders that fit into a skate wheel between the bearings. Their purpose is to reduce the weight distributed to each bearing, which can make your turns smoother and more stable and also extend the life of your bearings. Essentially they work in harmony with your bearings to help them spin efficiently while minimizing drag caused by the inner race rolling around the axle instead of staying stationary so the bearing can spin. Bearing spacers connect the two inner races to one another. And the inner truck washer also locks into the edge of the inner race. This locks all pieces together with the inner race to ensure that when you roll, you are spinning your bearings around the inner race, not spinning your inner race around your axle.
