Finding a roller chain that holds up in wet, outdoor, or chemically exposed environments is a persistent challenge for engineers, maintenance technicians, and serious DIYers. This stainless steel simplex roller chain is built for exactly those conditions — delivering reliable power transmission where carbon steel chains would corrode and fail prematurely.
Available in both 304 and 201 stainless steel grades, this simplex roller chain conforms to ISO/BS standard dimensions across a wide size range — from compact 04C up to heavy-duty 20A. Lengths are offered in 1M (~39.4 in) and 1.524M (~60 in / 5 ft) cuts, with select sizes also available in pre-counted link configurations (e.g., 80-link, 96-link, 120-link, 160-link) for precise loop assembly without cutting.
Typical use cases include food-processing conveyor lines requiring stainless steel simplex roller chain for hygiene compliance, marine deck equipment and boat lift drives exposed to saltwater spray, agricultural machinery needing corrosion-resistant drive chain for outdoor operation, and light industrial automation where a standard ISO simplex roller chain replaces worn carbon steel runs.

Match the chain size to your existing sprocket's pitch. The number in the size designation corresponds to the ISO pitch: for example, 08B has a pitch of 12.7 mm (1/2 in), and 10A has a pitch of 15.875 mm (5/8 in). Check your sprocket's stamped markings or measure the center-to-center distance between two adjacent teeth to confirm the pitch before ordering.
304 stainless steel contains higher nickel content (~8–10%), giving it superior resistance to chlorides, acids, and saltwater — making it the preferred choice for marine, food-processing, and outdoor washdown environments. 201 stainless steel uses manganese in place of some nickel, offering good general rust resistance at a lower cost, and is well-suited for indoor or mildly humid applications where extreme corrosion resistance is not critical.
The 1M (~39.4 in) length is ideal for shorter drives or when you need to cut a custom length with a chain breaker tool. The 1.524M (~60 in / 5 ft) length — often listed with a pre-counted link number — is designed to close into a loop using a connecting link, making it convenient for fixed-center-distance drives such as bicycle-style or conveyor loop applications. Choose the pre-counted link variant if you want a ready-to-loop length without cutting.
The 304 stainless steel variants are well-suited for outdoor and marine environments where exposure to moisture, salt spray, or humidity is expected. Stainless steel roller chain resists surface rust and oxidation significantly better than standard carbon steel chain. For prolonged saltwater immersion or highly acidic environments, consider applying a compatible chain lubricant to extend service life further.
Stainless steel roller chains can operate with reduced lubrication in light-duty or low-speed applications, which is one advantage over carbon steel chains in clean environments. However, for moderate-to-high load or high-speed drives, periodic lubrication with a food-grade or stainless-compatible chain oil is recommended to minimize pin and bushing wear and extend chain life.
Yes — provided your sprockets are designed for the same ISO/BS simplex chain size. The pitch, roller diameter, and inner width of this chain conform to standard ISO dimensions, so it is a direct drop-in replacement for existing simplex drives. Always verify the chain size designation on your sprocket (e.g., 08B, 10A) matches the variant you select.
Yes. Standard simplex connecting links (also called master links) of the matching chain size can be used to join two lengths end-to-end or to close a loop. Ensure the connecting link is rated for the same chain size and material grade. Connecting links are sold separately and are not included with this chain.
