1. The type of misalignment
① Parallel misalignment : The driving shaft and driven shaft are parallel to each other but not on the same straight line.
② Angular misalignment : The driving shaft and driven shaft cross to each other but not on the same straight line.
③ Axial Misalignment : The driving shaft and driven shaft are on the same line but the distance between the two shaft vries.
(The permissible axial misalignment is ±25% of C)
④ Composite misalignment : The driving shaft and driven shaft do not cross to each other nor are they parallel to each other.
