Poor alignment or misalignment is the name given if the centrelines of two shafts don’t run in the same axis.
Poor alignment means:
- Premature bearing, seal, shaft and coupling failures
- High Bearing and coupling temperatures
- Excessive vibration
- Looseness of foundation bolts
- The breaking (or cracking) of shafts at, or close to the inboard
- High power consumption
Only 7% of measured machines within acceptable tolerances
A survey conducted by one of the world's leading rotating equipment service organizations shows that less than
10% of the 160 machines randomly chosen for measurement were found to be aligned within acceptable limits.
