In the context of misalignment, what does the "4-point" method refer to?

The "4-point" method is a specific technique used in alignment practices to effectively assess misalignment between shaft components. This method involves taking measurements at four distinct points along the rotational axis of the shafts being aligned. By measuring at these specific intervals—typically taken on both the horizontal and vertical planes—the technician can accurately determine the misalignment angles and offsets. This enhances the precision of the alignment process and helps to identify both angular and parallel misalignment.

Because this method utilizes multiple measurement points, it allows for a more comprehensive evaluation of the alignment, ensuring that any errors or discrepancies can be accurately addressed. Proper execution of the 4-point method is crucial for maintaining mechanical integrity and preventing premature wear on machinery.

While other options may relate to alignment methods or tools, the 4-point method distinctly focuses on the measurement aspect in assessing shaft misalignment.
