軸錯位故障會增加機器的計劃外停機時間，從而增加維護成本并造成生產損失。此外，軸錯位還會增加振動和摩擦，從而顯著增加能耗，并可能導致軸承過早失效。

傳統的對中方法雖然非常普遍，但往往無法達到當今精密機械所需的精確度。如今仍在使用的粗略對中方法，例如使用直尺和塞尺，雖然速度快，但可能不夠準確。另一種傳統的方法是使用千分表，雖然精度更高，但需要專業操作員，而且可能耗時。

Shaft misalignment breakdowns increase unplanned machinery downtime, resulting in higher maintenance costs and loss of production. Additionally, misaligned shafts can increase vibration levels and friction, which can significantly increase energy consumption and can cause premature bearing failures.

Traditional alignment methods, although very common, do not often produce the exacting degree of accuracy required by today’s precision machinery. The rough alignment methods still used nowadays, such as using a straight edge and feeler gauge, may be quick, but they can be inaccurate. Another traditional method employing dial indicators offers a higher degree of accuracy, but it requires specialist operators and can be time consuming.
