When standard carbon-steel chains corrode, seize, or fail in wet, chemical, or outdoor environments, engineers and makers pay the price in downtime and replacement costs. This 304 stainless double row roller chain is engineered for builders, fabricators, and machine designers who need reliable power transmission in conditions where ordinary chains fall short.
Each chain is manufactured from 304 stainless steel throughout — inner plates, outer plates, pins, bushings, and rollers — delivering consistent corrosion resistance across the entire assembly. Available in five ISO/ANSI double-row (duplex) sizes: 06B-2, 08B-2, 08A-2, 10A-2, and 12A-2, with a fixed length of 1.524 m (approximately 5 ft / 60 in) per piece. Pitch ranges from 9.525 mm (3/8 in) for 06B-2 up to 19.05 mm (3/4 in) for 12A-2.
Typical use cases include food-processing conveyor drives requiring washdown-safe stainless roller chain, marine and outdoor power transmission systems exposed to salt spray, and light-industrial automation rigs where a double-row duplex roller chain delivers higher load capacity in a compact sprocket envelope.
Plates, pins, bushings, and rollers are all 304 stainless steel, providing uniform corrosion resistance and eliminating the weak-point failures common in mixed-material chains.
The parallel dual-strand configuration roughly doubles the working load rating compared to a single-row chain of the same pitch, letting you transmit more power without upsizing the sprocket diameter.
Choose from 06B-2, 08B-2, 08A-2, 10A-2, or 12A-2 to match your existing sprocket set. Each size ships as a 1.524 m (5 ft) strand ready for cutting and connecting.
304 stainless resists rust in humid, wet, and mildly corrosive environments — suitable for food-adjacent machinery, outdoor conveyors, and marine-adjacent installations where carbon steel would corrode rapidly.
Accurately sized rollers seat cleanly on sprocket teeth, reducing impact loads, noise, and wear elongation over the service life of the chain.
The 1.524 m strand length accommodates a wide range of center distances. Use a standard chain breaker tool to cut to your required link count and connect with a matching duplex connecting link.

Match the chain size to your existing sprocket. The number before the letter indicates the pitch in eighths of an inch (e.g., 08 = 8/8 = 1 in pitch for A-series; B-series uses metric-origin pitches). The "-2" suffix confirms double-row. Check your sprocket's stamped designation or measure the tooth pitch to confirm compatibility before ordering.
B-series chains follow the ISO 606 standard common in European and international machinery, while A-series chains follow the ANSI B29.1 standard prevalent in North American equipment. Although some pitches overlap numerically, the inner width, roller diameter, and plate dimensions differ — they are not interchangeable. Always match the series to your sprocket standard.
304 stainless steel offers good tensile strength and is suitable for light-to-medium duty power transmission. It is not as hard as carbon steel after heat treatment, so for very high-load or high-speed drives, verify the breaking load of your selected size against your application's design load with an appropriate safety factor (typically 7:1 or higher for drive chains).
304 stainless steel performs well in fresh water, mild salt spray, and many dilute chemical environments. For prolonged immersion in seawater or exposure to chlorides and strong acids, 316 stainless steel is generally recommended. If your environment is borderline, consider periodic rinsing and lubrication to extend service life.
Yes. Even stainless roller chains benefit from lubrication at the pin-bushing interface to reduce wear and extend service life. Use a food-grade or stainless-compatible chain lubricant. In washdown environments, re-lubricate after each cleaning cycle.
You need a double-row (duplex) connecting link that matches your chain size and series (e.g., a 08B-2 duplex connecting link for 08B-2 chain). Stainless steel connecting links are recommended to maintain corrosion resistance across the full assembly. Standard carbon-steel connecting links will become the corrosion weak point.
Yes. Use a standard roller chain breaker tool sized for your chain pitch to press out a pin and shorten the strand to your required link count. Ensure you cut to an even number of pitches if using a standard connecting link, or use an offset link for odd-pitch lengths.
