Belting is the most expensive component of a conveying system. Superior’s Self-Aligning Idlers ensure that your conveyor belts stay on track, minimizing the chance of severe belt damage.

Concave in shape, the idler’s side guide rollers restrain the belt from running up and over the conveyor. In order to lessen the wear on the belt, the side guide rollers are made with high-grade HDPE that reduces the friction between the idler and belt.

  • Diameters 4″ – 7″ (101mm – 177mm)
  • Belt widths 18″ – 96″ (457mm – 2,438mm)
  • CEMA Classes: B, C, D, E and F
