A Series Short Pitch Precision Duplex Roller Chain

Huzhou Dongyao Chain Industry Co., Ltd. is one of the leading manufacturers and suppliers of a series short pitch precision duplex roller chain in China. With abundant experience, we warmly welcome you to buy high quality a series short pitch precision duplex roller chain from our factory. Also, custom service is available.

The DYLinkar A Series Short Pitch Precision Duplex Roller Chain is a high-strength industrial transmission chain strictly manufactured in accordance with the ANSI/ASME B29.1 and ISO 606 international standards. This chain is made of high-quality alloy steel and undergoes precise stamping, strengthening heat treatment, and shot peening treatment. The double-row structure significantly enhances its load-bearing capacity compared to single-row chains, enabling it to transfer greater power and operate more smoothly. The DYLinkar A series double-row roller chain is widely used in industrial fields such as construction machinery, mining and metallurgy, agricultural machinery, packaging machinery, food processing equipment, and automated conveying lines.

• Mining and metallurgical machinery equipment - Suitable for applications such as crushers, vibrating screens, scraper conveyors, and high-temperature sintering equipment in heavy-duty conditions.
• Agricultural machinery transmission system - Suitable for field operation equipment such as combine harvesters, seeders, and straw returning machines.
• Packaging and food processing conveyor lines - for the drive of automated packaging machines, sterilization tunnels, and bottle and can conveying chain plates.
• Construction machinery and logistics equipment – including stackers, lifting platforms, sorting conveyors and vertical parking garage lifting systems.

1. Comply strictly with the ANSI/ASME B29.1 international standard - the size specifications fully meet the requirements of the American Standard A series, and can be interchanged with any other brand of chains that also meet the same standard.
2. Specialized double-row sprocket system - The double-row structure requires the use of standard A-series double-row sprockets of the corresponding specification. They cannot be mixed with single-row sprockets. Ensure that each row of sprocket plates is evenly loaded and the meshing is reliable.
3. The installation dimensions are consistent with those of the single-row chain of the same series – the three basic installation dimensions, namely pitch (P), roller diameter (d₁), and inner width of the inner section (b₁), are exactly the same as those of the A-series single-row chain of the same model.
4. The connecting pieces must be compatible with the double-row configuration - the movable links and transition links need to be of the corresponding Duplex specification. Single-row connecting pieces cannot be used for the assembly and maintenance of double-row chains.
5. Wide range of alternatives to mainstream brand products of the same specification – Can directly replace products of the A series double-row roller chains from brands such as DID, Tsubaki, RK, KMC (such as ANSI 40-2, 50-2, 60-2, 80-2, etc.), suitable for the same specification replacement needs during equipment maintenance and repair.
