Conveyor Rollers: Choosing Between Steel, Nylon & Coated Options

Conveyor rollers are the unsung heroes of any material handling system. Whether moving parcels, heavy equipment, or delicate goods, the right roller can significantly impact your line’s efficiency, safety, and maintenance costs. But with materials like steel, nylon, and coated rollers available—how do you choose?

Understanding the Role of Conveyor Rollers

Conveyor rollers provide support and motion for belts or directly handle conveyed items in roller-based systems. Their primary functions include:

• Reducing friction

• Supporting load weight

• Maintaining belt tracking

• Absorbing shock and vibration

Material selection directly affects performance, durability, and operating costs.

1. Steel Rollers

Pros:

• Extremely durable and impact-resistant

• Ideal for heavy-duty and high-load applications

• Long service life under harsh environments

• High temperature resistance

Cons:

• Noisy operation

• Heavier weight increases energy consumption

• Not suitable for corrosive or cleanroom environments without special coatings

Best For:

• Mining and quarrying operations

• Industrial equipment manufacturing

• High-load conveyor sections in factories

2. Nylon Rollers

Pros:

• Lightweight and easy to install

• Quieter than steel rollers

• Resistant to chemicals, moisture, and many solvents

• Low friction surface for minimal wear

Cons:

• Lower load-bearing capacity

• Can warp under high heat or prolonged heavy loads

• May crack under sudden impact

Best For:

• Food processing lines (non-heated)

• Pharmaceuticals and cleanroom systems

• E-commerce fulfillment or light goods handling

3. Coated Rollers (Rubber or Urethane)

These are steel or nylon rollers with an outer coating designed to improve grip, reduce noise, or protect sensitive materials.

Pros:

• Excellent shock absorption

• Protects fragile goods during transfer

• Quiet and smooth operation

• Available in anti-static and food-safe variants

Cons:

• Coating can wear over time

• Higher upfront cost

• May not be suitable for abrasive environments

Best For:

• Packaging lines handling glass or electronics

• Inclined conveyors needing extra grip

• Pallet return or buffer zones

Maintenance Tips for Conveyor Rollers

• Inspect rollers monthly for wear or buildup

• Replace any rollers with excessive runout or surface cracks

• Keep lubrication schedules consistent for steel bearing housings

• For coated rollers, monitor for signs of peeling or soft spots

Common Mistakes to Avoid

• Overloading nylon rollers – leads to deformation or roller failure

• Using coated rollers in abrasive applications – coatings wear prematurely

• Skipping alignment checks – even the best rollers fail if the conveyor is misaligned
