Steel Idlers

Equal Troughing Idler Frame Superior, next generation idler

Longer Lasting Than Ever Before!

As a vertically-integrated company, Superior is one of the only conveyor manufacturers in the world to use our own components – like idlers, pulleys and scrapers – on our own conveyors. Each year, thousands of idler rolls and frames make the 30-second journey from one end of our manufacturing operation to the other.

This unique integration means we’re intimately connected to the success of our conveyor rolls and idlers. Our product development team consistently seeks feedback, performs tests and reviews conveyor service logs to understand idler performance and generate ideas for new technology.
