When a worn or snapped drive chain brings your conveyor, agricultural equipment, or industrial machine to a halt, every minute of downtime costs you. This simplex roller chain is engineered for makers, maintenance technicians, and machine builders who need a dependable, drop-in replacement or new-build drive solution across a range of standard pitch sizes.
Each length measures 1.524 meters (5 feet) and is available in five ISO-standard models: 06B-1, 08B-1, 10A-1, 06C-1, and 08A-1. Pitches span 9.525 mm (3/8 in) for 06B/06C, 12.7 mm (1/2 in) for 08B/08A, and 15.875 mm (5/8 in) for 10A. The chain is constructed from carbon steel with precision-hardened rollers and bushings, delivering consistent engagement and extended service life.
Typical use cases include light-to-medium conveyor drive systems, agricultural machinery replacement chains, go-kart and small-engine power transmission, and DIY automation rigs where standard ISO simplex chain sizing is required.
Choose from 06B-1, 08B-1, 10A-1, 06C-1, and 08A-1 to match your existing sprocket and drive system without modification.
Covers 9.525 mm, 12.7 mm, and 15.875 mm pitch sizes in a single product listing — one source for your most common simplex chain needs.
Hardened components reduce wear at the roller-sprocket interface, extending chain life under continuous or cyclic load conditions.
Industry-standard 5-foot roll length makes it straightforward to cut to your required loop size or join multiple lengths with a connecting link.
Solid carbon steel plates and pins provide the tensile strength needed for light-to-medium industrial and agricultural drive applications.
Suitable for conveyors, agricultural equipment, go-karts, small-engine drives, and DIY automation projects requiring ISO simplex chain.

Match the model number to your existing sprocket's pitch marking. If your sprocket is stamped 06B, select the 06B-1 chain (9.525 mm pitch). For 08B or 08A sprockets, choose the 12.7 mm pitch variant. For 10A sprockets, select the 15.875 mm pitch option. When in doubt, measure the center-to-center distance between three consecutive roller pins and divide by two to confirm pitch.
B-series chains (06B, 08B) follow the ISO/British standard, while A-series chains (10A, 06C, 08A) follow the ANSI/American standard. Both are simplex (single-strand) chains, but they differ slightly in inner width and plate dimensions. Always verify your sprocket standard before ordering to ensure proper engagement.
The chain is manufactured from carbon steel with a light oil coating for corrosion protection during storage and initial use. For prolonged outdoor or wet exposure, regular re-lubrication with a chain-specific lubricant is recommended. For highly corrosive environments, consider a stainless steel chain variant.
Yes. Standard ISO simplex connecting links (also called master links) are available separately and allow you to join multiple 1.524 m lengths or cut a single length to your required loop size. Ensure the connecting link matches the model and pitch of your chain.
Breaking load varies by model: 06B-1 is typically rated around 9.0 kN, 08B-1 around 17.8 kN, and 10A-1 around 22.2 kN. These are indicative ISO reference values; refer to the specific variant's datasheet or contact us to confirm the exact rated load for your application.
A chain breaker tool (chain press) is recommended for cleanly pressing out pins when shortening the chain to length. A connecting link and link clip or cotter pin are needed to close the loop. These tools are widely available at hardware and automotive stores and are compatible with standard ISO simplex chain sizes.
Lubricate the chain regularly with a dedicated chain oil or light machine oil, focusing on the roller-bushing interface. Check tension periodically — excessive sag or over-tightening both accelerate wear. Clean the chain with a degreaser when contaminated with dirt or grit before re-lubricating. Replace the chain when elongation exceeds 3% of nominal pitch length.
