Rotation driving units embed small magnets along the roll surface.
These magnets sometimes pop out due to centrifugal force caused by fast rotation. This is solved by inserting our thin seamless sleeve by air. Our metal seamless sleeves are tough and thin, 0.1mm and less, which covers magnets under any electrical properties.
