Bearing Spacers

Skateboard Bearing Spacers 8mm x 4 (1 sets) Bearing Spacers - What are they good for? When the axle nut is tightened down properly, they insure that when the wheel is rolling true and the bearings remain parallel to each other. In effect, the spacer sort of connects the inner rings of the bearings. Why is this good Because the bearing is actually designed to spin around the inner ring. Also, if the bearings are held parallel to each other, they don #39;t get tweaked in opposite directions when you are riding. Also, if the axle nut is tightened down firmly, the bearing will not move sideways in the wheel. Still confused as why you need them, you just do mate . Pack includes: 4 x WTRMLN Bearing Spacers (1 set)
