When a worn or snapped roller chain brings a conveyor, agricultural machine, or industrial drive to a standstill, every minute of downtime costs money. Engineers, maintenance technicians, and serious DIYers who need a direct-fit replacement for ANSI or BS-standard roller chains will find exactly what they need here — available in both 1.5 m and 5 m lengths, with matching CL connecting links and OL offset crank links sold in the same listing.
This listing covers a comprehensive range of roller chain models from 04C-1 through 40B-2, spanning simplex (single-strand) and duplex (double-strand) configurations. Chains are offered in 304 stainless steel, 201 stainless steel, and carbon steel to suit corrosive, food-adjacent, or heavy-load environments. Pitch dimensions range from approximately 6.35 mm (1/4 in) for 04C up to 50.8 mm (2 in) for 40-series chains, with roller widths and plate heights scaled to each standard model.
Typical applications include conveyor drive systems requiring a replacement roller chain for 08B-1 or 10A-1 sprockets, agricultural equipment needing a duplex 16A-2 chain upgrade, and light industrial machinery where a stainless steel 06B-1 roller chain resists wash-down corrosion. Connecting links (CL) and offset crank links (OL) in matching models let you close or shorten any chain run without specialist tooling.
Covers 04C-1 to 40B-2 across ANSI A-series and BS B-series standards — simplex and duplex — so one listing handles most drive replacement needs.
Choose 304 stainless steel for corrosion resistance, 201 stainless steel for a cost-balanced alternative, or carbon steel for maximum tensile strength in dry industrial environments.
1.5 m lengths suit short-run repairs and prototyping; 5 m rolls are ideal for longer conveyor runs or bulk stock, reducing per-metre cost.
Connecting links (CL Simplex/Duplex) and offset crank links (OL Simplex/Duplex) are available in the same model range, letting you close or adjust chain length without cutting tools.
Inner and outer plates are stamped to tight tolerances; rollers are hardened to reduce sprocket wear and extend service intervals in continuous-duty applications.
Suitable for conveyors, packaging lines, agricultural drives, go-karts, and general power-transmission equipment that specifies ANSI or BS roller chain standards.

Match the chain number stamped on your existing chain or sprocket to the model option in the dropdown. A-series designations (08A, 10A, 12A…) follow ANSI standards; B-series (06B, 08B, 10B…) follow BS/ISO standards. If you are unsure, measure the pitch (centre-to-centre distance between two pins) and the roller diameter, then cross-reference with a standard chain table.
Simplex chains have a single strand of rollers and suit single-strand sprockets. Duplex (double-strand) chains carry higher loads by running two parallel rows of rollers on a wider sprocket. Select simplex (-1 suffix) or duplex (-2 suffix) to match your sprocket specification.
304 stainless steel offers the best corrosion resistance and suits wet, food-adjacent, or outdoor environments. 201 stainless steel provides moderate corrosion resistance at a lower cost. Carbon steel delivers the highest tensile strength and is ideal for dry, high-load industrial drives where corrosion is not a concern.
A CL (connecting link) is used to join two ends of a chain to form a closed loop — it replaces the need for a chain press when assembling or repairing a drive. An OL (offset crank link) allows you to add or remove a single pitch from a chain run, useful when the required chain length falls between whole-link increments.
The 1.5 m and 5 m lengths are supplied as open-ended chain sections. You can use them as-is if the length matches your drive, or cut them to the required number of links using a chain breaker tool. Use a matching CL connecting link to close the loop after sizing.
Yes. Chains manufactured to ANSI or BS standards are dimensionally interchangeable with any sprocket that specifies the same chain number, regardless of brand. Always verify the pitch, roller diameter, and inner width match your sprocket's specification before fitting.
Select the CL or OL link that matches your chain's model number and strand count. For example, if you are running an 08B-1 simplex chain, choose the CL Connecting Link – Simplex in model 08B-1. For a 12A-2 duplex chain, choose the CL Connecting Link – Duplex in model 12A-2.
