SMART TOOTH technology is a visual identifier indicating when a sprocket has worn past its usable life. Wear indicator pins are strategically inserted into the thrust faces of the sprocket tooth where the resultant pressure angle of the chain roller creates wear. Eventually as the tooth profile recedes over time in service, the wear indicator pin becomes exposed visually identifying that it is time to for the sprocket to be replaced. Tsubaki SMART TOOTH offers users the ability to identify and schedule drive system maintenance. Predictable downtime is essential to cost effective part replacement ensuring critical component failure does not occur. » Learn More
