What are the two types of misalignment?

The identification of angular and parallel misalignment as the two types of misalignment is crucial in understanding how machinery systems interact and function. Angular misalignment occurs when the shafts of two coupled machines are not properly aligned in terms of angle; this misalignment can lead to stress and uneven wear on the bearings and other components. When shafts are angled, it creates a situation where the connection point is out of line, leading to increased vibration and potential failure.

On the other hand, parallel misalignment refers to a displacement of the shafts that occurs in a parallel manner, meaning that they are offset side to side, but remain on the same plane. This type often results in different loading characteristics across the connecting components, which can also lead to operational inefficiencies and damage over time.

Recognizing these two types of misalignment is essential for effective maintenance and preventive measures in machinery operation, as each type may require different approaches for correction and realignment to ensure optimal performance and prolong equipment life.
