Smart Sprockets with Wear Indicator Pins


U.S. Tsubaki Power Transmission has introduced its new Tsubaki Smart Tooth sprockets to the market, showcasing a patented Wear Indicator Technology that allows customers to identify and schedule drive system maintenance before critical component failure occurs.

The technology uses unique wear indicator pins located on one or more of the sprocket teeth that allow users to easily identify if the sprocket needs to be replaced.

Understanding when to replace a Smart Tooth sprocket is simple: friction from chain pressure wears down the material of a sprocket tooth and when the Wear Indicator pin becomes visible, it is time to replace the sprocket.

These wear indicator pins come standard on three sprocket teeth, ensuring that they are visible on any application no matter which part of the sprocket is covered.

Tsubaki has also included the latest laser etching technology in which Tsubaki Smart Tooth will be etched directly below each indicator pin providing even more visibility for the end user.
