Roller chains can be used for many years -- sometimes even decades -- before they wear enough to become problematic and need to be replaced. It can be difficult to tell when chains are becoming worn, and you certainly don't want to wait for your chains to break as they could damage important and expensive equipment . . . or individuals in your factory or other location! It's not uncommon for chains to wear unevenly depending on the external factors that are affecting the system, and environmental changes can also have an extreme effect on the lifecycle of your roller chains. With a handy roller chain stretch chart, you can determine if your chains are still doing well or if they are nearing the point where they need to be replaced.

How to Use a Roller Chain Stretch Chart

Chains can stretch?!? If the idea that strong metal has a great deal of flexibility to it is surprising, you're not alone. The amount of stretch possible in any roller chain depends on how it is used, how old the chain is and how long it's been in service. The type of service and conditions can also make a difference, which is why it's important to check a roller chain stretch chart to determine the best options for your unique project. You will often see wear start to show up between the chain pins and the bushings which eventually causes the chain to grow slightly longer over time -- or stretch. This can negatively impact the efficiency and effectiveness of the chain, causing additional noise to become a problem.

Do I Need to Replace My Roller Chains?

While it's not always possible to visually spot when chains start becoming slack, taking a few simple measurements will allow you to determine whether or not it's time to start looking for replacement chains. Predicting wear is difficult, as even the slightest difference in variables can cause chains to wear more quickly or to begin elongating. Regular roller chain checks are an essential part of your maintenance and one that's often overlooked. If you are starting to see visual wear spots, it's definitely time to replace your chains! And if you are replacing your chains, remember to replace those sprockets at the same time (remember, “PEER Perfectly Pairs”!
