Packaging conveying roller
Rollers of different materials
Duffy Machinery’s motorized telescopic roller conveyors are made to meet the tough requirements of today's warehouse logistics. Combining a strong carbon steel frame (which can be square or round) with top quality rollers and modern drive systems – including options for O-belt, Poly-V, or timing belt transmissions – these conveyor units offer a high-torque, virtually maintenance-free solution for loading and unloading.
Well thought-out for compactness and superior telescopic extension, our conveyors have been engineered to be able to go around obstacles and to be highly resistant to heavy impact while at the same time maintaining stability over the long period with the help of a simplified, low-maintenance mechanical structure. Having an excellent resistance to corrosion powder coating and highquality lockable swivel casters, Duffy's telescopic systems enable the change of manual bottlenecks into smooth, powered operational successes.

Customer concerns (FAQ)
1. What is the maximum load rating of your rollers and complete conveyor systems?
We have two levels of performance on offer: our Standard rollers can bear 100kg/㎡, whereas our Heavy-Duty rollers (1.5mm reinforced frames) can carry up to
150kg/㎡. Each roller is subjected to a 72-hour full-load continuous stress test to make sure it meets the highest standards of industrial reliability. We would be happy to offer you a tailored technical recommendation if you would share with us your exact cargo weight.
2. Do you provide custom sizing and specific packaging for assembly?
Absolutely! We customize products fully. Our width ranges from 300mm to 1500mm, and the lengths can be modular to fit any floor plan. We deliver our kits as
complete assemblies, and the "no-welding" design allows two people to finish installation within only a few hours.
3. What elements affect pricing and are there bulk incentives?
Prices depend on various factors such as type of material, load capability, dimensions, and special accessories. To facilitate large projects, we offer
5%-15% discounts for orders exceeding 100 meters and free site layout planning services.
4. What is the Minimum Order Quantity (MOQ)?
Our minimum order quantity for roller conveyor systems is 10 meters, which is appropriate for small-scale as well as full-facility distribution projects.
5. Which shipping methods can I use to ship international orders?
We do worldwide transportation with these logistics: Sea Freight (FCL/LCL), Cross-border Land Transport, and Air Freight of urgent spare parts or smaller components.
6. How do you prepare the goods for shipping abroad?
We have a very reliable triple protection system for shipping: the first layer is PE stretch film, then metal or wooden supporting frames, and the outer layer is made of ISPM-15 certified fumigation-free wooden crates.
7. What methods of payment do you accept?
We receive T/T (Telegraphic Transfer) and UnionPay as safe payment ways for all international business cooperation.
