The most common types are keyways (standard or Woodruff), precision pin holes, and registered flange faces. Keyways provide positive rotational locking, pin holes offer radial alignment, and flange faces ensure axial positioning.
Proper alignment features prevent angular drift, reduce wear on mating components, maintain consistent indexing accuracy, and minimize vibration. Poor alignment leads to premature failure, product misalignment, and reduced machine efficiency.
