Roller Chain Size Chart

Here we have put in order some of the most asked for roller chain configurations and sizes to steer your search for the roller chain that matches your specific needs in the right direction. Roller chain sizes and standards vary drastically from industry to industry and from one type of equipment to another. At times, it might get challenging not to make a mistake buying a replacement roller chain if you don't know the size standard name it goes by in the ANSI or ISO standards or its exact dimensions such as overall width, roller width and diameter, and plate height and thickness. The roller chain size charts below will help ensure that you purchase the chain that suits your machinery best and provides the strength or load carrying capacity that is required by your specific manufacturing process.

USA Roller Chain and Sprockets is one of the nations largest suppliers of roller chain and industrial PT components. Below is our Roller Chain Size Chart that shows a few of the different sizes we have, but our inventory is not limited to the roller chain size charts. Please note that each size under the "Chain Size" column is a clickable link to that specific roller chain size category so you can see the different qualities we offer (Economy, General Duty Plus, and Premier) along with the pricing.
