When a worn or undersized drive chain causes slippage, noise, or unexpected downtime on your conveyor, gearbox, or power-transmission system, finding a dimensionally accurate replacement matters. This single-strand roller chain is engineered for makers, maintenance technicians, and machine builders who need a reliable ISO-standard drive solution across a wide range of chain sizes — from the compact 04C up to the heavy-duty 16A.
Each chain is manufactured from carbon steel with a precision-formed roller and link-plate assembly. Available chain sizes span 04C through 16A (covering both metric B-series and ANSI A-series designations), with pitch dimensions ranging from approximately 6.35 mm (1/4 in) for 04C up to 25.4 mm (1 in) for 16A. Length options include 0.5 m, 1.524 m (standard 5-foot industrial roll), and 5 m cuts to suit your project scope.
Typical applications include agricultural equipment drive systems, light-to-medium industrial conveyor lines, go-kart and small engine power transmission, DIY automation rigs, and replacement drives on workshop machinery such as lathes, band saws, and drill presses.
Covers 04C, 05B, 06A, 06B, 06C, 08A, 08B, 10A, 12A, 12B, and 16A — one source for multiple machine sizes.
Solid carbon steel link plates and rollers deliver the tensile strength needed for continuous-duty drive applications.
Manufactured to ISO 606 / ANSI B29.1 dimensional tolerances for drop-in compatibility with standard sprockets.
Choose 0.5 m, 1.524 m, or 5 m cuts — order exactly what your project needs without excess waste.
Factory-applied lubricant on the roller bushings reduces break-in wear and extends service intervals in typical indoor drive environments.
Simplex configuration suits the majority of light-to-medium power-transmission applications and pairs with widely available single-strand sprockets.

Match the chain size to your existing sprocket's pitch and roller diameter. The size designation (e.g., 08B-1) encodes the pitch: the first two digits × 25.4 ÷ 16 = pitch in mm for B-series, or × 25.4 ÷ 8 for A-series. If you have the sprocket tooth count and shaft center distance, you can also calculate the required chain length. When in doubt, measure your worn chain's pitch with calipers.
A-series chains follow ANSI B29.1 and are common in North American equipment. B-series chains follow ISO 606 and are standard in European and Asian machinery. While some sizes share the same pitch, the roller diameter and inner width differ — they are not interchangeable. Always confirm the series your sprocket is designed for before ordering.
Carbon steel chains are best suited for indoor or sheltered drive applications. In wet, humid, or chemically exposed environments, the chain will require more frequent lubrication and inspection to prevent corrosion. For harsh outdoor use, consider stainless steel or nickel-plated chain alternatives, or apply a corrosion-inhibiting chain lubricant regularly.
Tensile strength varies by chain size — larger pitch sizes carry significantly higher loads. As a general reference, 06B-1 typically handles around 8.9 kN minimum tensile strength, while 16A-1 can exceed 60 kN. For precise working load limits, refer to the ISO 606 or ANSI B29.1 standard tables for your selected size, and apply an appropriate safety factor (typically 7:1 for dynamic loads).
Yes. Standard roller chains can be joined using a connecting link (also called a master link) of the matching chain size. If your required loop length falls between standard pitches, an offset link (half-link) can add one extra pitch. We recommend ordering a connecting link separately if one is not included — contact us to confirm availability for your chain size.
Measure the total chain length on your existing drive (count the links and multiply by pitch), or calculate using the sprocket center distance formula: L = 2C + (N+n)/2 + (N−n)²/(4π²C), where C is center distance in pitches, N and n are the tooth counts of the large and small sprockets. Round up to the nearest even number of links. Choose the 1.524 m or 5 m option if you need to cut to a custom length.
Yes. Although the chains are pre-lubricated at the factory, ongoing lubrication is essential for long service life. For light-duty or low-speed applications, manual brush or drip lubrication at regular intervals is sufficient. For higher-speed or continuous-duty drives, an oil bath or automatic lubrication system is recommended. Use a chain-specific oil — avoid thick greases that can attract abrasive particles.
