Double strand roller chain is also known as a “Duplex” is a double roller chain. Our double roller chain is manufactured to exceed the industry standards to ensure our roller chain keeps you running!

1. Meets and exceeds ANSI B29.1 Standards
2. Roller chain components are shot peened for greater fatigue resistance
3. Heat treated components for increased durability, longevity and wear resistance
4. Chain is pre-loaded (Pre-stretched) to eliminate initial stretching.
5. Chain components are lubricated before assembly, then dipped in a hot oil bath after assembly
6. Riveted Construction

SP Series Duplex Strands Roller Chain Applications

our double-strand roller chain can be applied to a slew of machinery for various drive systems and industries. 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. Roller chains are finding in a slew of applications and machinery!
(1) Factory machinery uses double-strand roller chains all over for various drive systems.
(2) Conveyor lines use double roller chains for heavy-duty roller, slat, and belt conveyors.
(3) Forestry applications such as lumber mills and paper mills use double-strand roller chains in their equipment.
(4) Various lifting machines, mechanisms, and equipment utilize double roller chains for their lifting needs.
(5) Double roller chains are used in agricultural equipment such as elevators, trenches, planters, and more.

Matching Double Strand Roller Chain Sprockets

This sprocket is a durable, high quality, and precision double roller sprocket with hardened teeth. Sprockets that have hardened teeth last longer and are much more durable than those that don’t. Something else that is notable about this sprocket is that it fully meets all ANSI Standards, which insures proper contact between the double roller chain and sprocket thus preventing premature wear or breakage. Sprocket is also black oxide coating which increases resistance to the environment and will prevent early rust build up. Sprockets with a stock bore comes with the standard hole with no keyway or set screws and can be easily machine bore to custom sizes. If you are needing a custom bore sprocket we have the capabilities on providing those to within a fast lead time and at really great prices.

Double Roller Chain Manufacturers

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 making with solid rollers to enhance rotation on the bushing and reduce impact loads. Even then, all the chain’s components with heat-treated to maximize strength, durability, longevity and wear resistance. What about the initial elongation that occurs with early chain usage, you say?

1.We have you covered.

2.We preload our roller chain during manufacturing to minimize that stretch.

3.We understand that any roller chains suffering from too much stretch early. Replace frequently, which significantly impacts the operation costs and productivity of your team.

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.

FAQ

Q1: What is a double-strand roller chain?
A: 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.
Q2: What is a duplex chain?
A: 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.
Q3: What is a 60-2 chain?
A: 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.
Q4: What is the strongest roller chain?
A: 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.

SP Series Roller Chain High Strength Short Pitch Roller Chains Duplex Strands

Through the overall optimization design of structural dimensions, parts materials, and heat treatment processing, its tensile strength is more than A series standard chain Increased by more than 28%, with excellent fatigue strength and impact resistance.
Double strand roller chain is also commonly referring to as a duplex roller chain and consists of two single strands of roller.

The benefit of a double roller chain is a high-strength chain with a relatively small form factor, the purpose of a chain is to transmit energy to the highest possible degree of efficiency. You’ll find that our roller chains not only have a high transmission of energy but are of superior quality and strength compared to other chains on the market. Stock standard carbon steel, stainless steel, nickel-plated, coated, and specialty double roller chains. We also stock sprockets, chain tools, and wear guides for duplex chains as well.
