The Best Reasons Why Roller Chains Fail and How to Prevent ...

It is critical to identify the failure mode and eliminate the cause. Overload, fatigue, rust and high speeds combined with small sprockets are the four main reasons roller chains fail. Overload and fatigue can be caused by galling, shock loading, misalignment or loads that are too high. A 10:1 safety factor is recommended.
