When sleeve bearing analysis is discussed in our industry it is typically inferred that proximity transducers are being utilized to directly measure shaft displacement within the bearing. Unlike casing mounted transducers used for routine data collection proximity transducers are usually permanently mounted on the machinery close to the bearing. These transducers are non-contacting devices which can directly measure the Peak-to-Peak displacement of the shaft as it rotates within its bearing support. In most cases, 2 proximity transducers are installed at a bearing location as an XY pair mounted at 90° to each other. This configuration thus allows for the analyst to determine planes of maximum and minimum motion along with the shape of the shaft motion within the bearing.

As we will see, the shape of the shaft motion along with procession will be important elements in determining machine condition in sleeve bearings. In many cases these parameters may be more important than the amplitude and frequency of the vibration. To correctly evaluate the shape and procession, it is very important that correct transducer convention be followed.
