Misalignment itself is a condition in the axle-clutch system when the two axes of the connected shafts are not in the same axis line. Misalignment is the main cause of vibration apart from unbalance. Misalignment can occur in bearings or in interconnected components such as couplings.
Misalignment is divided into two types, namely parallel and angular misalignment, but in most cases it is a combination of the two.
