轴错位故障会增加机器的计划外停机时间，从而增加维护成本并造成生产损失。此外，轴错位还会增加振动和摩擦，从而显著增加能耗，并可能导致轴承过早失效。

传统的对中方法虽然非常普遍，但往往无法达到当今精密机械所需的精确度。如今仍在使用的粗略对中方法，例如使用直尺和塞尺，虽然速度快，但可能不够准确。另一种传统的方法是使用千分表，虽然精度更高，但需要专业操作员，而且可能耗时。

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.
