When a standard carbon-steel chain corrodes, seizes, or contaminates a process, the cost of downtime far outweighs the cost of the right part. Engineers, maintenance technicians, and serious DIY builders who work around moisture, chemicals, food-grade environments, or outdoor exposure need a chain that holds up without constant re-lubrication or replacement. These duplex roller chains are manufactured to ISO/BS standards in A2/304 stainless steel, giving you the corrosion resistance of stainless with the mechanical strength of a precision roller chain.
Each length is 1.524 m (60 inches / 5 ft) of duplex (double-strand) roller chain. Available sizes span 06B-2, 08A-2, 08B-2, 10A-2, 12A-2, 16A-2, 20A-2, and 24A-2 — covering pitch ranges from approximately 9.525 mm (3/8 in) for 06B up to 38.1 mm (1½ in) for 24A. Inner width, roller diameter, and breaking load vary by size; refer to the variant selector for the specification that matches your sprocket.
Typical applications include food-processing conveyor lines where hygiene and washdown resistance are critical, marine and coastal machinery exposed to salt air, pharmaceutical or chemical plant drives requiring non-reactive hardware, and outdoor agricultural or garden equipment where weather resistance extends service life.

Match the chain pitch and strand width to your existing sprocket specification. The size designation (e.g., 08B-2) encodes the pitch: 08B has a pitch of 12.7 mm (½ in), while 08A has a pitch of 12.7 mm to the ANSI/A-series standard. Check your sprocket's bore plate or manufacturer datasheet for the chain number it accepts, then select the matching variant above.
A-series chains follow the ANSI/ASA standard (common in North America), while B-series chains follow the ISO/BS standard (common in Europe and internationally). Although both 08A and 08B share a 12.7 mm pitch, they differ in roller diameter and inner width, making them non-interchangeable. Always match the series to your sprocket standard.
A2/304 stainless steel offers good tensile strength suitable for many industrial drives, though its breaking load is typically 10–20% lower than an equivalent carbon-steel chain. For very high-load or high-speed applications, verify the working load against the chain's rated breaking load (see variant options) and apply an appropriate safety factor — typically 7:1 or higher for drive chains.
A2/304 stainless steel is widely used in food-grade and pharmaceutical conveyor applications due to its corrosion resistance and ease of cleaning. However, if your process requires FDA-compliant lubrication or full NSF certification, confirm that any lubricant you apply also meets those standards. The chain material itself is non-reactive with most mild cleaning agents.
Use a stainless steel duplex connecting link (also called a master link) of the same size and series as your chain. The connecting link clips onto the open ends of two chain lengths to form a continuous loop or extended run. Connecting links are sold separately — please specify your chain size when ordering to ensure compatibility.
Yes. While stainless steel resists corrosion, the pin-bushing-roller interface still requires lubrication to reduce wear and extend service life. Use a food-grade or stainless-compatible chain lubricant appropriate for your operating environment. In very wet or washdown conditions, re-lubricate more frequently as water can flush lubricant from the joints.
Each piece is supplied as a 1.524 m (60-link equivalent) length. To shorten it, use a chain breaker tool to remove the required number of links. To extend it, join multiple lengths with duplex connecting links. If you need a custom cut length or a bulk reel, please contact us to confirm availability.
