During a discussion with a colleague, I came to know that for motors with antifriction bearings, you only need one accelerometer to measure the vibrations, whereas for motors with sleeve bearings two accelerometers are needed (one for measurement in X direction and other for measurement in Y direction).
ALL bearings are "anti-friction", otherwise they would not be bearings.
There are basically two types of bearing: non-contact (e.g. magnetic) and contact. The contact typ ...
