It has been reported in the TAPPI journal that precision alignment resulted in extending bearing life by a factor of eight in a large class of rotating machines. Other reported benefits were a seven percent savings in overall maintenance costs and a twelve percent increase in machine availability. Machine breakdowns attributed to misalignment were cut in half.
Another benefit of precision alignment is a power saving. A recent study documented an average of eleven percent power saving by precision alignment in a group of simple pump-motor assemblies. This is because less power is expended in flexing the coupling, vibrating the machine, and heating the bearings. The dollar saving in this case due to reduced power consumption was more than twice the maintenance costs on these machines!
