Abstract - The neural network based approaches a feed
forward neural network trained with Back Propagation
technique was used for automatic diagnosis of defects in
bearings. Vibration time domain signals were collected from
a normal bearing and defective bearings under various speed
conditions. The signals were processed to obtain various
statistical parameters, which are good indicators of bearing
condition, then best features are selected from graphical
method and these inputs were used to train the neural
network and the output represented the bearing states. The
trained neural networks were used for the recognition of
bearing states. The results showed that the trained neural
networks were able to distinguish a normal bearing from
defective bearings with 83.33 % reliability. Moreover, the
network was able to classify the bearings into different
states with success rates better than those achieved with the
best among the state-of-the-art techniques.
