Choosing the right conveyor belt for your facility isn’t just about moving products from A to B – it can improve efficiency, safety, and long-term savings. Nobody wants a system that breaks down the minute the going gets tough. When conveyor belt selection goes wrong, you can face setbacks like increased maintenance, unexpected downtime, and rising costs.
A well-selected belt streamlines operations, handles the wear and tear of daily loads, and keeps things running smoothly. By being mindful of material compatibility, load capacity, and conveyor belt durability, you’ll help ensure your production line functions at its peak. In this blog we’ll dive into the fundamentals, explore different materials, and explain how to maintain your conveyor belts for optimal conveyor performance.
Critical factors in conveyor belt selection
Material compatibility
Think about the materials and conditions your belt will face each day. Are you working in a wet environment? Do you handle chemicals or pharmaceuticals? In these scenarios, conveyor belt materials need to be able to handle moisture or chemical exposure. Food-related operations need food-grade and easy-to-clean surfaces. Temperature swings in your facility can also be a big factor. If your belt isn’t designed to cope with the extremes in your warehouse, whether that’s heat from industrial ovens or near-freezing conditions in cold storage, it may degrade prematurely. By tailoring your belt materials to your operational environment, you’ll get more bang for your buck and reduce disruptions.
Load capacity and belt strength
No one wants to under-spec a belt. If your conveyor moves heavy products, you’ll need durable conveyor belts built for toughness. For lighter items like packaged food items or electronics, a more flexible, lightweight option might make more sense and save on power usage. It’s also important to consider how the load distributes along the belt. Miscalculated load capacities can strain the entire conveyor system, leading to hazards and more frequent repairs. Aligning belt specifications with the weight, volume, and product movements (with flow or across flow) directly impacts conveyor belt durability.
Environmental conditions
Environmental variables shouldn’t be overlooked. In high-humidity or chemically challenging areas, belts can degrade quickly if they’re not designed for those conditions. For example, if you’re in dairy or meat processing, constant washdowns are part of the job. A belt that absorbs moisture or is tricky to sanitise can introduce hygiene risks and will rust rapidly. On the other hand, extremely dusty sites—like certain grain or mineral processing plants—may need belts with anti-static or specialised surfaces that prevent excessive wear. Whether your environment is damp, dusty, or hot, conveyor belt selection is critical for smooth operations and compliance with safety or hygiene standards.
Overview of conveyor belt materials & designs
Rubber belts
Rubber belts are often seen in heavy-duty industries like quarries, mining, and large-scale manufacturing. They’re robust with excellent traction and can handle high-impact loads. But they’re not always the best choice for environments needing strict cleanliness, since rubber surfaces can be harder to sanitise. They’re also heavier, which can increase energy consumption.
Pros:
- Great load capacity and impressive durability
- Handles tough conditions and abrasive materials
- Strong traction and shock resistance.
Cons:
- Can be too heavy for certain applications
- Less suitable for high-hygiene industries.

Plastic modular belts
Plastic modular belts are designed for quick assembly and cleaning, making them popular in food processing, beverage bottling, and pharmaceuticals. They snap together, allowing you to replace one section without changing the entire belt. Their lower load capacity can be a limitation in heavy industries, but they shine in washdown environments where easy conveyor belt maintenance is paramount.
Pros:
- Easy to sanitise and repair
- Resistant to water, many chemicals, and mildew
- Ideal for frequent washdowns.
Cons:
- Not suited for very heavy loads
- May need more frequent segment checks in harsh conditions.
Fabric belts
Fabric belts are typically made from materials like polyester or nylon. They’re lightweight, flexible, and cost-effective. They can also come with various coatings to boost their performance for specific tasks. You’ll often find them in logistics centres or packaging facilities. While they may be less durable under extreme conditions, they work smoothly in moderate, everyday applications.
Pros:
- Lightweight, adaptable, and generally affordable
- Variety of finishes for different handling needs
- Easy to install.
Cons:
- Susceptible to wear if used with abrasive loads
- May not withstand demanding washdown or chemical conditions.
Expert insights and best practices
Investing in a top-of-the-line conveyor belt is worthless if maintenance is overlooked. A few consistent habits can make all the difference. Here’s what to do to ensure the best performance and longevity from your conveyor:
- Regular inspections. Spot and stop small issues like frays, misalignment, or abnormal wear before they become major problems.
- Preventative maintenance schedules. Follow a consistent routine to check tension, tracking, and any mechanical parts that can be prone to failure.
- Cleanliness and storage. Keep belts free of debris or residue. Store spare belts properly to avoid damage or contamination when they’re needed.
Proactive care not only helps sustain optimal conveyor performance but also lengthens the belt’s lifespan, avoiding expensive downtime.
