Weitspiral-Drahtgliedergurt Gruppe 300/400Wide-spiral-wire link belts Gr. 300 = spirals made of flat wire

Wide-spiral-wire link belts Gr. 400 = spirals made of round wire

Properties of the belts

  • The spirals of these belts are alternately wound clockwise and anti-clockwise. A straight belt motion is achieved by that to a large extent.
  • Through undulated cross rods, a precise adjustment of the spirals is achieved.
  • The large open area allows good penetration of air and liquids.
  • Smooth-running and flexible.
