In world industry one of leading places on application occupies the rotating machines. It can be: different gearboxes, pumps, electric motors, compressors and etc. One of most essential nodes of these machines is rolling bearing. So it is very important to look after rolling bearings condition, by the rolling bearing vibration monitoring without contact, and also it is necessary to conduct measurements on precision laser shaft alignment of rotating aggregates by the laser shaft alignment systems. A necessity in precision laser shaft alignment (it is regulation of shafts offset displacement in margins from 0,01 to 0,001 mm, and angular deviation with exactness from 0,01mm/100mm to 0,001mm/100 mm) arises up not only at high-speed aggregates (with the revolution numbers over 3000 rpm) but also at low-speed aggregates. For it, in the article described the experiment, which shows close connection between shaft alignment and vibration of rotating aggregates.
