How is vertical misalignment typically corrected?

Vertical misalignment occurs when the centers of two rotating shafts are not aligned in the vertical plane, which can lead to excessive wear, vibration, and potential failure of machinery. The common and most effective method for correcting vertical misalignment is by using shims underneath the machine feet.

Shims are thin pieces of material that are inserted under the feet of the machine to raise or lower specific points, effectively bringing the machine into alignment with the opposing shaft. This method allows precise adjustments to be made to correct the misalignment without the need to disassemble or relocate the entire machine. It is a direct and efficient way to ensure that the machinery is properly aligned to prevent operational issues and extend the lifespan of the equipment.

Other methods mentioned, such as adjusting motor speed or belts, do not address the root cause of vertical misalignment and may only mask the issue. While realigning the entire system could theoretically fix the problem, it often involves more complex procedures that can be time-consuming and unnecessary if shimming can effectively achieve the desired alignment.
