Mechanical alignment is a technique used in rotating machinery and equipment., for the purpose of aligning the faces of the couplings in the same plane, at any point. The purpose of alignment is to ensure the proper functioning of rotating equipment in order to eliminate vibrations, heating and give greater durability to the components.
Misalignments can be radial, angled or combined, either horizontally or vertically. See the full material:
