Metric Roller Chain Size Chart

USA Roller Chain and Sprockets is one of the industries leading suppliers of metric roller chains and other PT components. With all of our decades of experience manufacturing and working with roller chains, our team members have become established experts on metric roller chain sizes and how to identify the right chains for the right use cases.
The metric roller chain size charts below show some of the most popular metric roller chains we have, including:
Remember, however, that we stock more metric roller chain sizes and types than those shown in the charts below, such as our corrosion-resistant metric roller chains and our metric double pitch roller chains. If you don't see a metric roller chain in the size that you need, please give us a call or submit our Contact form. Also, note that the part numbers in blue on our metric roller chain size charts below are clickable links that will take you to the detailed product category page for the chain selected. Clicking these links will show you different quality options, pricing, and availability on the metric roller chains you’re looking for.
