The face and rim method is a widely recognized and traditional approach used in alignment tasks. It involves measuring the distance between the face of a coupling and the outer rim or edge of the coupling. This method is particularly advantageous due to its straightforward application, allowing technicians to determine the misalignment by assessing the variations between the coupling faces and rims.

This technique is often preferred in situations where advanced technologies may not be available or are not practical. It requires minimal equipment and can be effective for quick checks to ensure aligned machinery, particularly in field conditions. The ease of use and the ability to conduct assessments without complex setups contribute to its commonality in alignment practices.

Laser alignment tools, although highly accurate and increasingly popular, require more specialized training and equipment, which may not always be at hand, particularly in less sophisticated environments. Dial indicators and alignment bars, while useful, may not be as commonly adopted in various practical scenarios as the face and rim approach, which remains a staple in many maintenance operations.
