Roller Conveyors are material handling devices and use cylindrical rollers mounted within a frame to move goods.

They can be gravity roller conveyors, chain-driven or belt-driven, and each will suit one or more applications. Roller conveyors are common pieces of equipment in warehouses and manufacturing facilities.

Below, we look at how they work, the advantages of implementing them, and how to choose the best roller conveyor for your warehouse.

how does a roller conveyor work?

Roller conveyor operation is simple. Every roller comprises a frame, bearing, axle and steel outer tube.

The axle connects the rollers to the conveyor system, and the bearing enables them to turn quietly without any friction.

The system uses electricity or other energy sources to move the rollers in a continuous loop, and the outer tube keeps the items on track as they move along the conveyor.

types of roller conveyors

The main types of Roller Conveyors are gravity roller conveyors, motorised, heavy-duty rollers and flexible rollers. Below we look at each type in more depth.

Gravity Roller Conveyors

Gravity roller conveyors are unpowered conveyors that use the momentum of gravity to transport goods. The conveyor’s frame, which contains the rollers, is inclined slightly so no power is necessary. The rollers can then transport the items using only gravity.

Motorised Roller Conveyors

Motorised rollers are automated conveyors that move items from one location to another. Often, they connect two installations, such as a warehouse or production line facility. Unlike traditional conveyors, they’re equipped with electric motors that move pallets, boxes or other unit loads in a controlled motion. They’re made up of a series of rollers that support the load and transfer it along the circuit.

Curve Roller Conveyors

Curve conveyors are designed to transport boxes, cartons and other unit loads smoothly around corners within a conveyor system. They enable directional changes such as 45°, 90° or 180°, making them ideal for warehouses, distribution centres and manufacturing facilities with complex layouts or space constraints.

Heavy-duty Roller Conveyors

Heavy-duty conveyors for warehouses are designed to transport large, bulk materials and heavy items. Normally, they’re built from strong materials such as steel or aluminium and have reinforced frames, thicker rollers and other features.

Flexible Roller Conveyors

Flexible roller conveyors, commonly referred to as ‘flex conveyors’, are lightweight conveyors users can adjust to suit different situations and workflows. You’ll find them in production plants, but some companies use them in warehouses. Flexible roller conveyors can be motorised.

what are the benefits of conveyors?

Efficiency and Throughput

Roller Conveyors boost efficiency and throughput. Goods can travel substantial differences quickly, and the conveyor reduces bottlenecks and manual handling. Materials flow faster through the system and in larger amounts.

Improved Safety and Ergonomics

Roller Conveyors minimise manual handling and make it safer to handle large, bulky or heavy items. Operators can handle them more comfortably and at less risk of injury.

Roller Conveyor (5)

Flexibility and Scalability

Roller conveyors add flexibility to business processes and support growth. Businesses can move flexible roller conveyors around the facility and expand them as the warehouse grows larger.

Low Maintenance and Long Lifespan

Roller conveyors are easy to maintain because they have fewer moving parts than more complex systems. Gravity conveyors are especially convenient because they’re easy to clean.

Customisation

It’s possible to customise your roller conveyor to suit the needs of your business, especially in the case of flexible and telescopic conveyors.

how to choose the best roller conveyor for your warehouse

Load Type and Weight

One of the most important things to consider is the type of load you’ll be placing on the conveyor and its weight. Choose the roller diameter and material based on the heaviest loads. You’ll also need to consider the distance between loading and unloading points.

Conveyor Width and Roller Spacing

The material and load dimensions will determine your conveyor width, roller spacing and axle spacing. Base the conveyor belt width on the width of your largest items and add some space either side. As a rule of thumb, the conveyor should be 50 to 100 millimetres wider than your widest item.

Heavier, high-impact loads will require wider rollers, whereas smaller diameter rollers will suit lighter, low-impact loads. The length of the load will help determine roller spacing, and three rollers or more should always remain in contact with the load.

Throughput and Drive Requirements

What volume of goods are you working with? Gravity roller conveyors may be good for manual sorting and handling light items in low-to-medium volumes, but powered rollers are far more efficient when working with high volumes. They transport heavier loads at a consistent speed, which increases throughput and is beneficial for businesses that need to maintain more precise control over product flow.

Space and Layout

Gravity-powered conveyors require an incline to operate and are good for transporting light items over short distances. They’re cost-effective because they don’t require a power source and because they’re versatile and can adapt to different layouts.

Powered roller conveyors suit processes that require more automation. They can operate on flat paths or inclined ones, which makes them good for complex layouts or multilevel ones. It’s also possible to customise them better to the needs of the business, such as with sensors, controls and diverts, and connect them to other pieces of equipment.

Material and Environment

The conveyor material is important for durability. Steel is important for durability, and aluminium offers lightweight portability. Stainless steel makes cleaning easier and works well in heavy-duty systems. It’s also resistant to corrosion and rust.

Heavy-duty rollers are better for harsh industrial environments, whereas lighter duty ones work well in retail and small-scale warehousing. Plastic rollers work with gravity and powered systems and are easy to clean, although they tend to be used for systems handling lighter items.

Safety and Compliance

Conveyors must comply with a variety of safety standards. In terms of mechanical safety, these include guards and covers over drive areas and pinch points, and easily accessible emergency stop buttons. Load limits must be marked clearly, and side guides and railings must be present to stop objects falling off.

Cost and Maintenance

Powered roller conveyors tend to be more expensive because of the upfront investment required and additional costs, including energy, (specialised) maintenance and moving parts.

Gravity-powered roller conveyors’ non-reliance on electricity makes them less expensive, and their simple design lowers installation costs and maintenance frequency.

applications of roller conveyors in warehouses

Goods-in and Dispatch Areas

You’ll commonly find roller conveyors in areas where the facility receives goods or dispatches them from the warehouse. The conveyors streamline loading and unloading at the docks and cut out much manual handling.

You’ll find them in preloading areas, where logistics teams are preparing goods, especially pallets, for loading, or at the loading area itself and transporting the goods into trailers or from them. 

Picking and Packing Zones

Roller conveyors connect different areas of the warehouse, including picking and packing zones. The conveyors help to connect workstations efficiently and move materials between them quickly.

Roller Conveyor (2)

Assembly or Sorting Lines

Roller conveyors are common in assembly lines, where goods are produced in high volumes, or sorting systems, where the system separates goods or materials and directs them to different areas.

Integration with Automation or Manual Workstations

Warehouses are having to become ever more efficient, and many combine their conveyors with other equipment to keep processes running smoothly. They’ll integrate automated conveyors into their systems, automated solutions or with their manual workstations.

tips for implementing your warehouse conveyor system

Map Your Material Flow

When implementing a conveyor for a warehouse, the layout is crucial. Identify where the conveyor will save you the most time and where it will eliminate bottlenecks. Sound planning is essential to ensure the conveyor doesn’t hinder operations.

Ensure Proper Roller Spacing and Alignment

Roller spacing and alignment is important for smooth flow of materials. At least three rollers should sit underneath the material being conveyed. This provides a stable base and distributes the weight more evenly. It also ensures the weight doesn’t exceed the load capacity of individual rollers.

Regular Maintenance and Inspection

Regular maintenance is crucial to keep operations running and prevent unplanned stoppages (not to mention unforeseen expense). This means inspecting belt or roller alignment and adjusting them so that the conveyor runs smoothly. It also means inspecting the belt or rollers for any signs of wear or damaging and repairing them or outright replacing them. Bearings and other moving components should be lubricated to reduce friction and prolong their lifespan.

Plan for Scalability

When incorporating a roller conveyor into operations, consider growth and scalability. Systems like ours enable your business to adapt its warehouse loading to changes in layout and growth in demand so that you can continue operations without necessarily moving to a larger building.

Roller conveyors, especially powered roller conveyors, allow businesses to scale up, improve operational safety and boost throughput and productivity. However, costs and maintenance are significant factors to consider and, in the case of powered rollers, entail a major investment upfront. Businesses that go ahead with the purchase can enjoy a long-term ROI.

As well as the benefits stated, businesses that invest in a Powered Roller Conveyor will lower the downtime of machinery in their places of business, which contributes to productivity as the conveyor is in operation more time. Otherwise, they’d have to call out an engineer for unplanned repairs, which can increase the downtime and the cost if the engineer has to order parts from a supplier, wait for them to arrive and then install them.

We offer a range of Conveyors and Maintenance Services to support our clients. If you’re looking to enjoy the benefits of installing a roller conveyor at your warehouse, contact us by email at hello@joloda.com, call us on 0151 427 8954 or message us via our contact form below and we’ll be happy to advise you.

frequently asked questions (FAQ)

Are roller conveyors suitable for heavy loads?

Roller conveyors are specially designed to handle heavy loads because they’re made of durable materials. Powered roller conveyors allow businesses to transfer high volumes over longer distances.

Do roller conveyors require power to operate?

Gravity-powered roller conveyors don’t need power to operate because they rely on an incline and gravity to transfer them. Powered ones do, which creates extra expense but also offers huge business benefits.

Can roller conveyors be adjusted or expanded?

Scalability is one of the benefits of roller conveyors. Businesses can configure them in different lengths and widths to meet their needs. They can also customise them with guards, emergency stops and other features, both to suit the needs of the business and to make them safer.

What is a roller conveyor?

A roller conveyor is a material handling system that uses a series of rotating cylindrical rollers mounted in a frame to move goods along a set path.

Roller conveyors are commonly used in warehouses, distribution centres and manufacturing facilities to transport boxes, pallets and other unit loads efficiently, either by gravity or powered motion.

What are the different types of roller conveyors?

The main types of roller conveyors include gravity roller conveyors, motorised roller conveyors, chain-driven roller conveyors, heavy-duty roller conveyors, flexible roller conveyors and curve conveyors.

Each type is designed for specific applications, load weights and throughput requirements, ranging from manual handling to fully automated warehouse operations.

What is roller pitch?

Roller pitch is the distance between the centre points of adjacent rollers on a roller conveyor. Correct roller pitch ensures stable load support and smooth movement; as a general rule, at least three rollers should always be in contact with the load to prevent tipping or uneven travel.
