• The research in this paper aimed to show the importance of axial alignment on the example of maintaining a technical system. In this paper, the importance of alignment is examined on industrial fans. The technical system on which the alignment was performed reached the anticipated bearing life of 23,650 operating hours prescribed by the manufacturer, while the technical system on which the alignment was not performed was exposed to excessive load by a misalignment shaft. As a result, it did not meet the expected technical expectations, and it canceled at 5,400 hours of work. Research has shown that the application of alignment can increase the service life of bearings by 4.38 times on axles on which no alignment has been performed. Implementation of modern maintenance concepts, using appropriate methods of technical diagnostics aim to optimize the operation of industrial systems for a short period of time and with as few downtimes as possible. The authors of the paper presented the method of laser alignment in order to bring the industrial fan system into optimal operation. In addition to laser alignment, the condition of the system was checked by vibro diagnostics, before and after access by laser method. The paper presents all measurements performed with vibration analysis devices as well as a visual display of the state of the system during the laser alignment check of an industrial fan. Misalignment leads to incorrect operation, which in the case of electric motors and fans is most often reflected in damage in the form of distortion of the shaft or damage to the bearings.
