Self-Aligning Idler

40 Series Idler | Superior Industries

hold the line

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

Service & Parts

We always have been and always will be a privately-owned company. That means we can add more employees to our customer service team without Wall Street breathing down our neck. Isn’t that the way it should be?

dealer support

They’re the same neighbors you’d trust to babysit your dog on the weekend. Our factory-trained dealers are a local connection for sales, service and parts.

phone support

Staffed by agents born to serve others, you’re welcome to call our technical service team 24/7/365. (If you call in the middle of the night, we can’t guarantee they’re in uniform!)

replacement parts

You know the old saying…”square pegs don’t fit in round holes?” It’s often the case with knock-off parts. Genuine Superior parts are forged from the same steel as our equipment
