Guide bearings task is to ensure stable dynamic and static behaviour of the rotor in all operating conditions. Therefore monitoring the forces applied on bearing through the oil film is very important for bearing health tracking. Bearing stiffness, support and seals can deteriorate in exploitation. This measurements are best suited in combination with Relative Shaft vibrations.
Absolute bearing Vibration measurements are conducted using accelerometers or velocity meters positioned in two perpendicular directions.
On thrust bearings sensors can be placed in axial direction to monitor the load on axial bearing.
