Whether you are building a food-adjacent conveyor, a marine-environment drive, a chemical-processing line, or a long-service DIY machine, this simplex roller chain in 304 (A2) stainless steel keeps running where ordinary chain fails. Available in six ANSI\/ISO models from the compact #25 (04C-1) up to the heavy-duty #80 (16A-1), it covers the full range of light-to-medium power transmission needs.\u003c\/p\u003e\n    \u003cp\u003eEach chain is manufactured to ANSI\/ISO simplex (single-strand) standards in 304 stainless steel — equivalent to A2 grade — offering solid corrosion resistance across a wide range of environments. Pitch sizes span 1\/4 inch (6.35 mm) for the #25 model through 1 inch (25.4 mm) for the #80 model, with intermediate pitches of 3\/8 in (9.525 mm), 1\/2 in (12.7 mm), 5\/8 in (15.875 mm), and 3\/4 in (19.05 mm). Length options of 1 m, 1.5 m, and 5 m let you order exactly what the job requires.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include food-processing conveyor drives where hygiene matters, outdoor power-transmission systems exposed to rain and humidity, aquaculture and marine equipment subject to salt-air exposure, and workshop or maker-space machines where long service intervals are a priority.

Like all roller chains, stainless steel simplex chain benefits from periodic lubrication to reduce pin and bushing wear and extend service life. Use a food-grade lubricant if the chain is used near food products, or a standard chain oil for general machinery.
