Winder wheel over the line and applied over silk textile machinery parts, is a common thread through the other parts over the line. Line of ceramic wheel structure is to trap the bearing out. When the wire, wire in the ceramic surface through the ring, the ceramic ring with wire, line rotation, which will convert the static friction sliding friction. But at the start and stop, to overcome the inertia, there will be local sliding friction.
