Misalignment between the motor and the mechanism is a hidden cause of vibration and bearing wear. Let's figure out how to perform a alignment check.
What is alignment
Alignment is the coincidence of the axes of the motor shaft and the driven mechanism. When misaligned, the axes are shifted or at an angle, which creates alternating loads on the bearings and coupling.
What is the threat of misalignment
- Increased vibration.
- Accelerated wear of bearings.
- Destruction of the coupling.
- Shaft fatigue cracks.

Signs of misalignment
Indirectly, misalignment is caused by vibration, which remains during coasting (mechanical) and changes when the fasteners are tightened. Often vibration diagnostics spectrum indicates misalignment.
Alignment checks are performed after each installation and replacement of bearings. Elimination - alignment with engine position adjustment. Timely alignment saves bearings from premature wear.
