Whether you're a maintenance engineer keeping a production line running, a workshop owner repairing agricultural equipment, or a maker building a custom power-transmission system, finding the right roller chain in the correct pitch and strand configuration shouldn't be a struggle. This listing covers a comprehensive range of ISO-standard simplex and duplex roller chains — #80 (16A\/16B), #100 (20A), and #120 (24A) — along with matching full buckle and half buckle connecting links, so you can source chain and hardware in one order.\u003c\/p\u003e\n    \u003cp\u003eEach roller chain section is supplied in a 1.5-meter (approx. 59 in) length and is manufactured to ISO 606 \/ ANSI B29.1 dimensional standards. The #80 \/ 16A and 16B series feature a 25.4 mm (1 in) pitch; the #100 \/ 20A series steps up to a 31.75 mm (1.25 in) pitch; and the #120 \/ 24A series runs at a 38.1 mm (1.5 in) pitch. Roller diameter, inner plate width, and pin diameter all conform to the respective ISO series, ensuring drop-in compatibility with standard sprockets of the same designation.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include replacement drive chains on industrial conveyor systems, power-transmission upgrades on agricultural machinery such as combine harvesters and balers, custom chain-drive builds for go-karts and mini-bikes, and maintenance of packaging or bottling line equipment.
