Apart from unbalance, the second most common sources of machine failure are misalignment and coupling errors. These can be overcome by laser alignment of couplings, increasing the efficiency and lifetime of the machine.

Poorly aligned shafts are responsible for many machine problems: Reported tests have shown that incorrect alignment is the cause of up to 50% of machine breakdowns. Poor alignment or a misalignment is the name given if the centrelines of two shafts don’t run in the same axis.

Poor alignment means:

• Rise in machine vibrations
• Increased in bearing wear
• Greater wear of sealing elements
• Excessive wear of the coupling
• Higher energy consumption

The resulting downtime, production loss and repair result in high costs. Precise alignment of shafts not only saves money, but also pays in the long term with trouble-free machine operation.
