Drive Wheels for Conveyor Systems: What to Consider

Wheel-based conveyor systems depend on consistent traction, alignment and rolling performance. An unsuitable wheel can cause slipping, vibration, uneven wear, carrier misalignment or unplanned shutdowns. However, “conveyor wheel” can refer to several different components, so buyers must first confirm whether the application needs a powered drive wheel, a load-carrying track wheel or a guide roller.

WSCS supplies standard and custom drive wheels for conveyor systems and polyurethane guide rollers for overhead conveyors, rail-guided transfer systems, friction lines, turntables, lifters and other automated production equipment.

Which Conveyor Components Use Industrial Wheels?

• Overhead conveyor track wheels: support carriers as they travel along steel rails.

• Friction drive wheels: transmit torque by pressing against a rail, carrier or rotating component.

• Guide rollers: control lateral position and keep equipment aligned with the track.

• Transfer-table wheels: move fixtures and products between production stations.

• Drum support and drive wheels: support or rotate drums used in processing equipment.

This article does not refer to a belt conveyor drive pulley or chain sprocket. The guidance below applies to wheels that run on tracks, support carriers or transmit motion through direct surface contact.

Key Conveyor Wheel Selection Factors

How to Select Conveyor Drive and Track Wheels

1. Identify Whether the Wheel Drives or Follows

A powered wheel must transmit torque without slipping or moving on the shaft. Its bore, keyway, flange or clamping connection must match the drive unit.

A non-powered track wheel normally requires bearings, low rolling resistance and impact resistance. Guide rollers usually carry lower vertical loads but experience continuous lateral contact and alignment stress.

2. Calculate the Actual Load per Wheel

Include the carrier, fixture, product and any impact created by track joints or transfer points. Loads may not be shared equally, especially on curves, uneven rails or multi-wheel assemblies.

Selection should therefore consider dynamic load and concentrated load rather than total conveyor weight alone.

3. Review Track Joints, Curves and Surface Damage

Welds, rail joints and gaps can repeatedly strike the wheel tread. A material with good straight-line abrasion resistance may still crack or lose chunks if its impact and tear resistance are unsuitable.

Wheel diameter, tread thickness, material formulation and track maintenance all affect performance over rail joints.

4. Balance Traction and Rolling Resistance

Friction drive wheels need enough grip to start and control the conveyor. Supporting track wheels should roll efficiently with limited heat generation.

A softer tread may improve contact but increase deformation and rolling resistance. A harder tread may improve dimensional stability but provide less cushioning over joints.

5. Control Roundness and Runout

Excessive radial runout can cause speed variation, vibration and unstable carrier movement. Synchronized transfer systems may also require controlled diameter consistency between paired wheels.

Buyers should identify which tolerances directly affect carrier position, feed rate or product alignment.

6. Evaluate Continuous-Duty Heat

Continuous loading and repeated tread deformation generate internal heat. Risk increases with higher load, speed, thick tread sections and frequent acceleration.

The wheel should be evaluated under its intended operating cycle rather than by static load capacity alone.

Polyurethane, Rubber or Nylon Conveyor Wheels?

Polyurethane conveyor wheels are commonly used for conveyor tracks and friction drives because suitable formulations can combine load capacity, wear resistance, tear resistance, dimensional stability and controlled rolling resistance.

• Polyurethane: suitable for high loads, repeated travel and wheels with bonded metal hubs.

• Rubber: considered where cushioning, vibration control or grip is the main priority.

• Nylon: provides low rolling resistance and corrosion resistance, but noise and impact conditions must be reviewed.

The correct material depends on the track, load, speed, contamination and maintenance conditions. Material name or hardness alone cannot predict service life.

Hub, Bearing and Tread Options

• Steel, cast-iron, aluminum or engineering-plastic wheel cores

• Keyed bores, flanges, bolt patterns and custom shaft connections

• Ball bearings, bushings or plain bores for non-powered wheels

• Flat, crowned, flanged, grooved or custom tread profiles

• Different polyurethane hardness and performance formulations

• Corrosion protection for wet or washdown environments

New production equipment often requires custom conveyor wheels because the track profile, hub connection or operating environment does not match a standard product. WSCS can evaluate designs from drawings, operating data or an existing sample.

Common Conveyor Wheel Failures

• Chunking at track joints: review impact, tear resistance, wheel diameter and rail condition.

• Uneven wear: inspect alignment, roundness, bearings and load distribution.

• Slipping: check surface contamination, contact pressure, tread material and drive torque.

• Delamination: investigate hub preparation, corrosion, heat and excessive shear stress.

• Wobble or vibration: measure runout, bearing clearance and track alignment.

• Overheating: review load, speed, tread thickness and continuous runtime.

Frequently Asked Questions

Is a conveyor drive wheel the same as a drive pulley?

No. A drive pulley moves a conveyor belt, while the wheels discussed here run on a track, support a carrier or transmit motion through direct surface contact.

Why do polyurethane conveyor wheels lose chunks?

Common causes include repeated impact at rail joints, sharp track damage, unsuitable tear resistance, misalignment and excessive lateral stress.

Can WSCS reproduce a conveyor wheel from a sample?

Yes. A worn sample should be reviewed together with track dimensions, load, speed and failure history so the original design can be reconstructed correctly.
