Steel Rolls
Challenge Everything
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.
If our steel idler rolls aren’t good enough for our own conveyors they’re definitely not good enough for you. Our pursuit of the perfect idler continues …

Models – Idler Rolls
STEEL ROLL STYLES
CEMA Rolls
These rolls meet or exceed standards developed and published by the Conveyor Equipment Manufacturer’s Association.
DT Rolls
Double Tube design features inner and outer steel tubes giving the rolls increased rigidity for higher load ratings.

Longer-Lasting
IDLERS
In Real-World Conditions
In addition to improving the proven performance of our standard idler seal, 5+ years of trial and error produced an exclusive line of Application-Specific SpinGuard® Seals.
WEt
Wash or dredge processes. Frequent washdowns.
dry
Crushing and screening producing dust with minimal fines.
eco
Overland or long distance material handling sites.
titanium™
Washed sand, fines removal or dredging. Most extreme conditions.
standard
Traditional material handling not described above. Typically 80-90% of applications.
Idler Styles
TROUGHING idlers
Equal Troughing
Three identical length rolls for 90% of applications.
UNEqual Troughing
Wide center roll for flat belt applications where material is sorted or picked.
Self-Aligner
Constantly pivots so a mistracking belt is forced to a central position.
NEw Project
Maintain load rating while customizing rolls and frame to meet budget in large projects.
Offset Center
Often used in grain handling, the center roll position eliminates a pinch point to protect the belt.
Feeder / Picking
Wide center roll for flat belt applications where material is sorted or picked.
Flat Carrier
100% flat belt applications where the belt does not form a trough.
Low Profile
Available in a standard or channel frame mount for applications with height restrictions.
Wire Rope
Offset center roll with a frame designed for wire rope installations typically in overland applications.
Variable Pitch
Adjustable height outside rolls designed to protect belts from sharp transitions.
Retrofit Rolls
Superior manufactured rolls specially-designed for competitor brand frames.
custom
If you constantly fight disruption and maintenance using standard designs, we encourage you to contact us for custom rolls and idlers.
RETURN IDLER Styles
Standard
Return Roll
Single steel roll for applications with no previous maintenance issues.
Self-Aligner
Return Idler
Constantly pivots so a mistracking belt is forced to a central position.
V-Return
Return Idler
Manage high capacities while aligning the belt on long distance overland conveyors.
beater bar
Return Roll
Steel rods create a beating motion to free the belt of carryback material.
Live Shaft
Return Roll
Fixed to the roll, shaft rotates with the idler and are usually used as carriers on a feeder conveyor.

Project Idlers
Don’t blow your budget on overdesigned idlers. Knowing the load rating, we’ll custom-select the frame and rolls in an economical approach to idler selection.
Idler Classes
From light to heavy to extreme, we build conveyor idlers for a broad set of material handling applications.
