What can cause premature failure of a coupling?

Premature failure of a coupling is often linked to incorrect alignment or overload conditions. When a coupling is misaligned, it can lead to excessive stresses and imbalances during operation, which can rapidly wear out the components. Additionally, overload situations, where the coupling is subjected to forces beyond its design specifications, can also result in failure. This excessive strain can cause components to deform, wear unevenly, or fail altogether. Correct alignment ensures that forces are distributed evenly through the coupling, and operating within designed load limits is crucial for longevity.

While oversizing may lead to inefficiencies or underperformance, it is not a direct cause of premature failure. Proper lubricating practices and using high-quality materials are crucial for the longevity of couplings, but they don't address the fundamental issues of alignment and load that can lead to early failures. These factors highlight the importance of installation accuracy and adherence to manufacturer's specifications to ensure the reliable operation of couplings.
