Which is more difficult to correct, angular or parallel misalignment?

Angular misalignment is generally considered more difficult to correct due to the specific adjustments needed to achieve precise alignment. When equipment is angularly misaligned, it results in the shafts being at an incorrect angle relative to each other. This can lead to increased wear and tear on components, higher vibration levels, and potential failures if not corrected accurately.

Correcting angular misalignment often requires a more thorough understanding of the connection between the components and a greater precision in adjustment. This is because simply shifting one component does not typically result in both components being properly aligned; rather, a combination of horizontal and vertical adjustments may be necessary. These adjustments must be made carefully to prevent disrupting the overall alignment further.

In contrast, parallel misalignment primarily involves ensuring that the two shafts remain parallel to one another, which can often be corrected with simpler adjustments. This doesn’t usually require the same level of precision as angular misalignment, making it relatively easier to address.

Therefore, the inherent complexity and precision required for adjusting angular misalignment is why it is seen as more challenging to correct compared to parallel misalignment.
