Why do some wheels of SEBA HV roller skates shake from side to side? The amplitude of the shaking is very small, and you can only see the shaking if you look carefully. .

Bearing problem, because seba hv is self-assembled, so if it is not high imitation, it must be that your bearing is not tightened. After all, if the shoes of 1200 are genuine, there can be no problem of insufficient workmanship.

The specific method is to tighten the bearing and tool rest as much as possible, and tighten the inner bearing to clamp the spindle.
