A belt conveyor carries products on a continuous moving surface; roller conveyors support loads on a series of rollers and may be gravity-fed or powered. Compare the product base, size, route, speed, transfers, accumulation, controls and maintenance against the conveyor maker's specifications.
Choose a conveyor around the load and the route. Belts provide a continuous carrying surface, while rollers create discrete support points and can be gravity-fed or powered.
Compare the conveyor types
| Factor | Belt conveyor | Roller conveyor |
|---|---|---|
| Product support | Continuous belt surface | Individual rollers under the load |
| Product base | Compare shape, bottom surface and belt material | Confirm the load spans and runs on the roller layout |
| Route options | Straight sections and inclines are available in model-specific systems | Straight sections, curves, merges and transfers vary by platform |
| Accumulation | Depends on belt zones, controls and product handling | May use zones or controlled rollers, depending on design |
| Maintenance | Belt condition, tracking and tension per maker guidance | Roller condition, drive elements, bearings and zone controls |
Interroll’s modular conveyor platform lists both belt and roller modules, including non-powered roller modules. The exact load limits, speed, environment, dimensions and controls are specific to each module and configuration.
Layout checklist
- Measure the product’s length, width, height, weight and base condition.
- Mark each straight, curve, incline, transfer, merge and stop location.
- Identify required speed, spacing, accumulation and release behavior.
- Check the manufacturer’s load, dimensions, drive, control and environment data.
- Include access, guarding, emergency stops and maintenance points in the layout review.
- Have a qualified integrator review the conveyor and surrounding machine interfaces.
OSHA’s general machine-guarding rule includes hazards such as ingoing nip points and moving parts. Check the requirements that apply to the industry and site. For connected material movement, see AMRs vs AGVs and automation ROI planning. Browse conveyors and material handling.

Common questions
When should I compare a belt and roller conveyor?
Compare them when selecting a unit-handling route. Product dimensions, base, transfer points, accumulation and controls help define which module fits.
Are roller conveyors always gravity-fed?
No. Some roller modules are non-powered and others use driven rollers. Confirm the specific conveyor design.
What safety review does a conveyor need?
Review the complete application, guarding, access and applicable local requirements with a qualified engineer or integrator.
