Miniature Roller Chain

Miniature Roller Chain

Miniature series roller chains are manufactured for applications that requite an ultra-small drive or conveyor chain that will work in extremely limited spaces. Ranging from pitch size 0.125" to 0.25" we have the widest range selection of miniature roller chains available. At USA Roller Chain we realize the importance of precision when it comes to small parts, this is why our miniature chains are manufactured with the utmost precision and tightest possible tolerances. We also use high-quality metals in these chains for long-term superior performance and durability. Besides the chain, we also supply miniature roller chain sprockets.
