Engineers, fabricators, and DIY builders who need a compact, dependable #25 roller chain will find this 04C-1 transmission chain engineered to perform where it counts — in tight drive systems that demand consistent pitch accuracy and long service life.\u003c\/p\u003e\n    \u003cp\u003eThis #25 roller chain conforms to the 04C-1 standard with a pitch of 1\/4\" (6.35 mm). It is available in two materials — a common carbon steel option for general indoor applications and a stainless steel option for environments exposed to moisture, mild chemicals, or outdoor conditions. Length options range from 0.5 m (~1.6 ft) up to 5 m (~16.4 ft), with individual connecting links also available for quick field repairs.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include go-kart and mini-bike final drives, small conveyor systems, robotics and automation rigs, bicycle derailleur conversions, and light agricultural equipment — anywhere a compact #25 pitch roller chain for precision power transmission is required.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits all standard #25 \/ 04C-1 sprockets with 6.35 mm pitch.
