When a worn or undersized drive chain causes slippage, noise, or unexpected downtime on your equipment, finding a correctly sized replacement fast is critical. Whether you are a maintenance technician keeping industrial conveyors running or a maker building a custom power-transmission system, this roller chain is engineered to deliver consistent, low-stretch performance across a wide range of loads.
This transmission chain is constructed from manganese steel, offering a balance of tensile strength and wear resistance suited to demanding drive applications. Available in single-row (simplex) and double-row (duplex) configurations, models range from compact 04C up to heavy-duty 32A, with lengths of 1M (≈39.4 in) and 1.5M (≈59.1 in) to suit different drive spans.
Typical use cases include roller chain drive systems for go-karts and mini bikes, conveyor line replacement chains in light industrial settings, and custom reduction drive builds for robotics or agricultural equipment where a reliable single-row or double-row roller chain is required.

The letter suffix indicates the standard: B-series follows the ISO 606 (British/European) standard, while A-series follows the ANSI B29.1 (American) standard. Although both series share the same pitch within a size number, their roller diameter, inner width, and plate dimensions differ. Match the model to the standard your sprocket was designed for — check your sprocket's markings or datasheet to confirm.
A single-row (simplex) chain has one strand of rollers and is used for standard power-transmission loads. A double-row (duplex) chain has two parallel strands sharing the same pins, roughly doubling the load capacity for the same pitch. Choose duplex when your drive requires higher torque transfer in a compact sprocket diameter, or when a simplex chain would need to be upsized to a larger pitch.
Manganese steel provides solid tensile strength and surface hardness that resists wear from repeated roller-sprocket engagement. Exact minimum breaking load values vary by model and are specified per ISO 606 / ANSI B29.1 standards for each chain number. For specific load ratings, please contact us with your model number and we will provide the datasheet values.
Manganese steel roller chains are not inherently stainless and will oxidize if exposed to moisture without lubrication. For outdoor or humid environments, regular lubrication with a chain-compatible oil or grease is strongly recommended to prevent rust and maintain performance. If your application requires inherent corrosion resistance (e.g., food processing or marine environments), consider a stainless steel chain instead.
Yes, provided your sprocket is designed for the same chain number and standard (ISO 606 or ANSI B29.1). Check the chain number stamped on your sprocket or in its documentation and select the matching model variant above. Key dimensions to verify are pitch, roller diameter, and inner width — these must match between chain and sprocket for correct engagement.
Yes. The chain is supplied as a cut length and requires a connecting link (also called a master link) to form a closed loop on your drive. Connecting links are sold separately and must match your chain's model number and standard. Please contact us to confirm the correct connecting link for your selected variant.
Measure the required chain length by calculating the center distance between your drive and driven sprockets, then add the wrap length around both sprockets. As a rule of thumb, order slightly longer than your calculated requirement so you can trim to the exact link count needed. The 1M length suits shorter center distances (e.g., compact gearbox drives), while 1.5M covers most standard machinery and conveyor spans.
