Packaging conveying roller
Rollers of different materials
Designed to produce industrial logistics equipment that is capable of bearing heavy loads for a long time: standard rollers are made of ≥2.5mm high-frequency welded precision steel pipes, assuring outstanding structural strength and dynamic balance in addition to that. Surface finish options available: galvanized for anti-corrosion purposes, or polyurethane coated for enhanced friction and noise reduction. 304/316 stainless steel variants that are both food-grade and sufficient for use in corrosive environments. All of them are equipped with IP66 sealed and pre-lubricated deep groove ball bearings, which guarantee smooth, low-torque, long lifespan operation.
Expansion ratio: 530:1000 / 530:1250 / 740:2000
Transmission speed: 10 - 30 m/min
Key Features & Advantages
Heavy duty swivel casters with multi-point braking system
Front/middle/rear brakes, standard 4-inch size: In contrast to the competitors' single-brake casters, our design is capable of precise steering and immediate locking, thus reducing by 30% the time for transfer between loading ports and workstations.
More manual operation, Less electric drive
Discard layout circuit costs and electricity expenses, and are capable of providing up to 1.6x times more ROI than motorized conveyor alternatives—perfect for budget-conscious operations.
Plug-and-play design
Don't worry about assembly or calibration—by contrast to competitors that require more than 4 hours of setup, our expandable conveyor lines (expansion ratio 530:1000 to 740:2000) are ready for use straight from the box.
Fortified carbon steel skeleton
It is powerful enough to resist the impacts of industrial handling at high intensity levels thanks to 3232+2525 square tube racks (≥1.5mm electrophoretic black thickness) and galvanized rollers (diameter 50mm, spacing 50/75/100mm), while its lifetime is 25% longer than standard aluminum-frame models.

Our User Case
In Bozhou, Anhui, a leading pharmaceutical center in China, a major company there was facing difficulties in terms of order fulfillment delay and heavy pressure of the drug traceability. They decided to collaborate with Zhangzhou Duffy Machinery when exploring a more intelligent way to move the working process.
Duffy Machinery tailored a mechanical system consisting of powered roller conveyors, lift-and-transfer units, and DWS technology. Conveyor belts serve as the main artery of the warehouse, while the transfer units not only guide individual boxes but also pallets towards the respective gates. Simultaneously, the DWS system conducts automatic scanning and weighing of all items via conveyor.
The change was reflected in very short time. By mechanizing the split-case and full-box ship areas, the company reduced manual work that was prone to errors and witnessed a rise in daily turnover. And, each package has been digitalized in terms of weight, size and purpose of delivery. This allows the company to be in compliance with stringent medical laws and, most importantly, refer to patient safety as the foremost priority of their medication operations. This cooperation goes to show that properly chosen automation is not only about speeding up things—it is about building a more reliable supply chain.
Multi-industry application
1
Core Drive & Load-Bearing for Conveyor Systems
As the "bones and joints" of automated logistics lines, our rollers not only serve as electric drum drives (providing power to belt/goods motion at 10-30m/min) but also as load-bearing parts, carrying the weight of goods while handling the transport direction— which is a very important aspect of smooth material flow.
2
Gravity Storage Racks & Flow Rack Systems
By lowering shelves to a sloped position and using our rollers, goods move from one end to the other by simply sliding down due to gravity. This FIFO (First In, First Out) operation method helps increase storage capacity and raises picking efficiency by 40%—a perfect solution for boxed/crated goods with high turnover in warehouses and distribution centers.
3
Production Line Positioning & Alignment
Designed with very specialized roller layouts, our machines perform a variety of functions such as correcting the positioning of the goods, changing movement direction, and centering the load mid-transport. This ensures that packaging stations, assembly lines, or inspection points receive accurately aligned goods and helps reduce the production downtime caused by manual intervention.
4
Specialized Industrial Environments
Manufactured using carbon steel (galvanized) or stainless steel, our rollers meet food/pharma safety standards and are corrosion-resistant. Heavy-duty versions of the rollers can continuously hold very heavy materials such as steel coils and pallets and can be used in heavy industry/plant conditions.
Factory Certificate
We hold 42 authoritative industry certifications, such as ISO9001, CE, and EACC, to guarantee product safety and international standards.
Our engineering team consists of 18 specialists across R&D, design, installation, and after-sales support.
From initial technical blueprints to final maintenance, we provide a comprehensive one-stop service to streamline your project.
Customer concerns (FAQ)
1. What is the maximum load-bearing capacity of a single roller and the entire track?
Here is what we have in terms of load capacity for our load-bearing industrial solutions Dynamic load capacity: Standard model 100kg/㎡, heavy-duty model up to 150kg/㎡ (wall thickness 1.5mm). All rollers have been through the 72-hour full-load fatigue test and test reports are available. Kindly tell us about the weight your goods generally have, and we will be able to advise on the best specification.
2. Can the width and length of the conveyor be customized? How should it be packaged and transported to facilitate on-site assembly?
We provide full size options and good on-field assembly solutions Size customization: The width (300-1500mm) and length (modularly increased or decreased) can both be customized. Modular design, on-site splicing, and extension are also available. Packaging and transportation: Packaged as a complete modular kit, including pre-assembled frame sections, the correct number of rollers, connectors, and tools. With color-coded installation diagrams attached, a two-person team can normally finish the assembly within a few hours even without the help of professional welders.
3. What factors are the pricing based on? Are there any bulk discounts for large-scale projects?
Pricing is based on several factors that both you and we can benefit from our transparent and flexible strategy The quote mainly depends on the material (e.g., stainless steel > galvanized), load-bearing specifications, custom length/width, and special accessories. Bulk discount: In the case of project procurement, we offer a tier discount. For example, if a single order length exceeds 100 meters, a special discount of 5-15% can be given. Value-added services: We provide free layout design consultation and load analysis so that you have control over your total cost with the optimal configuration.
4. What is the Minimum Order Quantity (MOQ) for your conveyors?
Our MOQ is quite flexible to be able to accommodate small projects as well as large-scale industrial setups: Inclined Belt Conveyors (Climbing Machines): Minimum 1 unit.
Roller Conveyors: Minimum 10 Meter. Note: We have tiered pricing system for bulk orders. Please contact our sales team for a custom quote.
5. What types of shipping do you offer?
We can adapt to your schedule and budget by offering worldwide logistics solutions: Sea Freight (FCL/LCL): Cheapest option for big conveyor systems. Land Transport: Best for cross-border delivery in nearby regions. Air Freight: Quick shipping available for urgent parts or small items.
6. How do you pack your equipment for international shipping?
Ensuring your equipment is safe even when shipped over long distances is our top priority. Here is what our default export packaging consists of: Inner Layer: PE stretch film professional to keep away moisture and dust. Support: Heavy-duty metal or wood integrated stand (footings) for the movement stability. Outer Layer: Wooden crates that comply with ISPM-15 and are fumigation-free, providing a very powerful protection against impact.
7. What payment methods you accept?
We accept safe and transparent payment terms T/T (Telegraphic Transfer) and UnionPay.
