Guard Gear - Online Condition Monitoring

Guard Gear

Guard Gear

The most optimal maintenance strategy is condition-based maintenance.  For the most critical machines, online condition monitoring gives more reliability and service actions can be taken only when needed. In many industrial processes gearboxes are often critical components. As a forerunning gearbox manufacturer, we at Kumera Drives have developed a gearbox condition monitoring device.

Technical data

Guard Gear is designed for diagnosing industrial gearboxes. The function of Guard Gear is based on measuring parameters that indicate incipient failure of mechanical components and lubrication oil. These are:

  • Vibration
  • Lubrication oil
  • Quality
  • Level
  • Temperature
  • Rotational speed 

It is possible to attach optional sensors measuring, for example, humidity, viscosity, or particles of lubrication oil. Load or torque information from the process can be monitored with Guard Gear. Warning and alarm limits can be set for all variables. Measurement results are automatically saved into the external cloud database. 


The user interface is web browser based, it is possible to use with an Ethernet connection or wirelessly. Gearbox information and documents (part list, assembly drawing, etc.) will be saved.  There is also available a field for notes, into which observations or, for example, gear unit service history can be written.

If you are interested in online gearbox condition monitoring, please contact Kumera Drives sales department so we can survey if Guard Gear is a solution for your needs.
