The interpretation of what chain wear elongation (“stretch”) is and how it can be accurately
measured is a common issue when determining chain wear. Some customers utilize tape measures to determine chain stretch. Others will use their own internal best practices and estimates to determine if the life of the chain has been exhausted.

Tsubaki® Chain Wear Indicators are designed to measure roller chain condition and determine critical wear. The indicator tools are made of a high-quality material to withstand harsh and corrosive environments. The strong construction of the indicator tools ensures accurate measurements of the chains every time.

This tool is for ANSI and British Standard chains.
