A simple method for directly measuring bearing wear has been developed by means of an eddy-current displacement sensor. The system consists of a sensor head unit, including a displacement sensor and aluminum functioning foil as a target metal, a data processing system including an amplifier, an A/D converter of 14 bits, a personal computer, and a display. The error of this system was approximately 2 μm, which is sufficient for practical use. Another error caused by the system when used in a plant is discussed theoretically, and a method for the correct estimation of bearing wear without this error based on smoothing, i.e., an averaging of the sampling data, is proposed.
