Discovering why belts fail


Sep 02, 2009

If you're replacing the belts on your drives as often as twice a year, ask yourself why. Each time a belt breaks, don't just replace and discard it. Synchronous belt failure results in ever-decreasing performance and often costly belt replacement. A careful diagnosis of your drive’s underlying issues, however, will ultimately save you money and maintenance time.

The culprit could be misalignment, an under-designed drive, an incorrect belt-to-sheave fit or maybe even old metal components. Sheaves and sprockets that haven't been replaced in more than eight years are beyond their useful life. To identify causes of failure and find recommendations on corrective measures, download the Synchronous Belt Failure Analysis Guide.

From belt crimping damage and high belt installation tension to sprocket misalignment and adverse environmental conditions, this guide walks you through how to identify the reasons behind premature failure and makes recommendations on corrective and preventive measures.
