Revolutionary condition monitoring for spindles and rotating shafts


The basis for most industrial machines is a rotating shaft. Whether we have tool machines like milling or grinding machines, production machines like printing presses, support aggregates like pumps, or fans in mind - they all have rotation in common.

Sooner or later an additional movement escorts the rotation: the movement of the axis in the rotation plane. This movement is found in the wear of the bearings. The more torque and unaligned forces the bearing has to cope with, the sooner this effect appears. The worst case scenario is that the bearing collapses and blocks the movement of the spindle. A comparison of the spindle condition between during and after a time period can help to predict serious faults.

Gyrometric Systems developed a technique which can permanently monitor the condition of rotation between 15 and 20,000 rpm at a resolution of 0.1µm.

For the integration into applications there is a wide variety of sensors which can be used to implement Gyrometric Systems technology in gear boxes, grinding spindles and wind turbines. A permanent monitoring of critical or very expensive components and setting limits to axial play. Torsional vibrations or speed variations helps to extend the lifetime and minimize the support cost.



  • GyroMech mobile equipment for testing spindles
  • integration in applications for permanent monitoring
  • 15 up to 20,000 revolutions per minute (soon up to 100,000rpm)
  • 0.1µm resolution of the axial play
  • monitoring of torsional vibrations
  • analysis of speed variations (within one revolution)
  • permanent monitoring via LAN or GSM network
  • interpretation and comparisson with historical data
  • waterfall diagram for the analysis of critical rpm areas
  • optimization or error analysis of gear boxes and clutches
  • cost effective standard components lead to an easy integration


The GyroMech flyer contains all the facts for condition monitoring on spindles with the mobile GyroMech of Gyrometric Systems.
