A misalignment in machinery often leads to a higher risk of breakdown because components that are not properly aligned can cause excessive stress and strain on bearings, shafts, and other mechanical parts. This misalignment can result in uneven loads being distributed across the machinery, leading to premature wear, overheating, and ultimately, mechanical failure. When parts are not properly aligned, they may rub against one another or operate outside of their design tolerances, increasing the likelihood of breakdowns and operational interruptions. Recognizing and correcting misalignments in machinery is therefore critical for maintaining reliability and longevity of equipment.
