ANSI Standard Double-Strand Roller Chain

The double-strand roller chain, commonly called a duplex roller chain, consists of two rows of single-strand roller chains manufactured together. It provides lots of practicality due to its high impact strength coupled with a relatively small form factor. You can be sure that this chain will transmit your machine’s energy to the highest possible degree of efficiency.

What professionals love about this double roller chain is that it exceeds the standards for ANSI B29.1 chains, and its components are perfect for resisting fatigue over time. Those components are also treated by heat, which can increase their longevity, durability and resistance to wear and tear over time. We know that special care is needed for these materials to keep any sort of outside materials like dirt to keep them from working.

Roller Chain Made To Last

ANSI Standard Double-Strand Roller Chain

High energy transmission is not the only area our double-stranded roller chain shines, though. Its superior quality and strength trump many others on the market. Our double strand roller chain is made with solid rollers to enhance rotation on the bushing and reduce impact loads. Even then, all the chain’s components are heat-treated to maximize strength, durability, longevity and wear resistance. What about the initial elongation that occurs with early chain usage, you say? We have you covered. We preload our roller chain during manufacturing to minimize that stretch. We understand that any roller chains suffering from too much stretch early on will need to be replaced frequently, which significantly impacts the operation costs and productivity of your team.

Opportunities for Variety With Chains and Attachments

At PEER Chain, variety is the order of the day, as we stock standard stainless steel, carbon steel, nickel-plated, and ProCoat double roller chains. Because different types of roller chains like carbon are good for more heavy-duty work, it’s important to note that we offer a wide variety of options for our customers. In addition, we have sprockets and attachments like the S attachment, G attachment, DD-3 attachment and WA-1 wide contour attachment to improve your use cases further. On the topic of variety, our double-stranded roller chains range from sizes 35 to 240, and the average tensile strengths go from as low as 4,938 lbs to as high as 308,647 lbs.

Join the Chain Revolution

Are you worried about industry standards? Our double-strand roller chain is manufactured in accordance with the B29.1 standards of the American National Standards Institution (ANSI). These specifications can help bridge the gap of transmissible power for roller chains. So, you can be sure that we do not allow room for any sort of compromise on strength, performance or the manufacturing process used. That’s right; if you get a PEER Chain double-stranded roller chain, you can directly interchange it with third-party chains that also use ANSI manufacturing guidelines, even if they are from different manufacturers. This also means that you don’t have to worry about sprockets and attachments either, as just about any tools that conform to ANSI standards will fit the bill. Our roller chains are suitable for construction of all sorts for new plants and machines.

Finding the Right Attachments

ANSI Standard Double-Strand Roller Chain

Speaking of attachments, we have agricultural chain G and S attachments, ANSI standard roller chain DD-3 attachment, ANSI standard roller chain WA-1 wide contour attachments, and more — for all your use cases.

Furthermore, our double-strand roller chain can be applied to a slew of machinery for various drive systems and industries. In forestry, double-strand roller chains are commonly used in lumber mill and paper mill equipment. In agriculture, double-strand roller chains find use in equipment like trenches, elevators and planters. Various lifting machines and equipment also incorporate double-strand roller chains for their lifting needs. In addition, industries that deal with construction, food, sugar, wastewater and many more make use of double-strand roller chains. Conveyor lines especially use double-strand roller chains for heavy-duty slat, roller and belt conveyors.

What sets PEER Chain apart from the other chain companies is our high level of dedication to providing top-of-the-line customer service to our customers. Be sure to contact us whenever you have a problem with your chains, and we’ll be more than happy to help.

Frequently Asked Questions

What is a double-strand roller chain?
These types of roller chains are also known as duplex roller chains in the industry. The double-strand roller chain is made up of two roller chain strains manufactured together. One of the benefits of using a double-strand roller chain is that it boasts a ton of power but with a fairly small factor for form. After all, the purpose of this type of chain — and other roller chains — is to transmit energy at as high of a degree as possible to be efficient.

What is a duplex chain?
A duplex roller chain is one that has a separate row of plates that provides the same number of teeth slots for sprockets that runs parallel to the other two rows of plates in a simplex model; it also has pins and roller bearings in between. There is yet another row of plates on the triplex variants, making four plates in total with enough space to fit three sprockets.

What is a 60-2 chain?
The 60-2 roller chain is considered a duplex chain that has a ¾ pitch. These are usually manufactured with ANSI specifications. The most basic function of these chains is to transport power to the highest degree they can. They set the bar high for other chains because they provide users with the highest level of performance, strength and precision.

What is the strongest roller chain?
The best roller chain is one that’s stainless steel. It’s regarded as the most valuable because the integrity of its structure allows it to withstand all kinds of environmental stress as time passes. They’re used frequently when rust is a possibility. They also differ from carbon steel chains because the parts are higher-grade and can be used for chemicals, food applications, medical uses and more.
