JW Bell is proud to offer Superior conveyor parts, where they’re goal is to develop and manufacture a premium product. It’s the uniqueness and problem-solving characteristics of Superior idlers, pulleys and other homemade accessories that truly set apart Superior conveyors.
Idlers
Idlers are to conveyors as foundations are to buildings: constant, reliable support. Superior idlers create reliable foundations.
For proper operation, idlers need a sophisticated seal to protect their bearings in all conditions. Second, conveyor owners need a variety of models and options to handle and endure application-specific environments. Third, idler consumers require a modern manufacturer who is built to respond quickly.
Steel Rolls
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.
Rubber Rolls
Rubber Troughing Idlers

Rubber Equal
Three identical-length rolls for 90% of applications.

Rubber Unequal
Wide center roll for flat belt applications where material is sorted or picked.

Rubber Offset Center
Often used in grain handling, the center roll position eliminates a pinch point to protect the belt.

Rubber Feeder / Picking
Wide center roll for flat belt applications where material is sorted or picked.

Rubber Flat Carrier
100% flat belt applications where the belt does not form a trough.

Rubber Low Profile
Available in a standard or channel frame mount for applications with height restrictions.

Rubber Wire Rope
Offset center roll with a frame designed for underground wire rope installations.

Rubber Variable Pitch
Adjustable height outside rolls designed to protect belts from sharp transitions.
Rubber Return Idler Styles

Rubber Disc Return Roll
Single roll for applications with no previous maintenance issues.

Rubber V-Return Roll
Manage high capacities while aligning the belt on long distance overland conveyors.

Rubber Fixed Roll
Fixed to the roll, the shaft rotates with the idler and usually used as carriers on feed conveyors.
Urathon Rolls

Standard Roll
- Urethane-based tires
- Reject sticky material
- Last 3X longer than rubber

Spiral Roll
- Same characteristics of standard
- Cleans belts as it rotates
- Complete urethane coverage

Beater Roll
- Lobed discs install to steel roll
- Discs cause light vibration
- Removes carryback material
Drum and Wing Pulleys
The “driver” is usually the most important component of any moving system and it’s no different with conveyors. Simply put, conveyor pulleys are responsible for driving the belt.
It takes at least two to travel and are categorized as drive or head, return or tail, bend tensioning, snub tensioning or take-up pulleys. Maximum pulley life is essential to cost-efficient material handling and high-capacity production.
Wing Pulleys
Invented and first introduced by Superior more than two decades ago, the Chevron Wing Pulley has greatly expanded the service life for thousands of rolls of conveyor belting.
That’s because its unique V-shape sheds fugitive materials more effectively, minimizing the risk of rocks and other unwanted items from getting trapped between the pulley’s wings. Once material is trapped, it can put holes in your belts and cause wings to fold or bend.
Don’t settle for outdated technology. Upgrade to the Chevron Pulley and unlock new levels of reliability and longevity for your conveyor system.

Drum Pulleys
Drum pulleys are one of the most versatile components of a conveyor system. Depending on their specifications, they can serve in a variety of roles or positions, including drive or head, return or tail, bend tensioning, snub tensioning and/or take-up pulleys, which increase or decrease the amount of slack in your conveyor belt.
Maximum pulley life is essential to cost-efficient material handling and high-capacity production. Importantly, a manufacturer’s approach to pulley design, manufacturing and proper application has a direct effect upon pulley reliability or potential pulley failure.

Impact
Did you know a conveyor’s load zone — also known as its transfer zone — is the most suspect to maintenance issues?
It’s where the slightest adjustment can lead to material spillage, which is a costly error for your operation. These conveyor components are designed to maintain order in your load zone.
Impact Beds
Constructed with energy-absorbing materials, the impact bed is designed to protect conveyor belting from the beating of falling material within the load zone.
Actually, the material doesn’t always need to be big and lumpy. Sometimes, impact beds are used to soften the blow of material from extended distances as it free falls from discharge chute to hopper target.
- Belt widths 24” or 72” (609 – 1,828mm)
- Lengths 4′ – 5′ (1.2m or 1.5m)
- Standard Duty: up to 200 lbs/ft (91kg)
