-: ABSTRACT:-
Bearings are valuable.... until they go bad, and then they are worthless. But the definition of Bad Condition of Bearing is not standardized yet. To quickly discover what bearings may be salvaged, we offers positive testing machine. Because “A Bearing Saved is a Bearing Earned”. We tried to compare the bearings on ideal and defective condition on Sound and Vibration factor. For Sound we used microphone and for Vibrations we implemented piezoelectric sensor. Instead of manually comparing we further given the data to computer for automatic test of bearing. By this we reduced manual errors. By this we can predict life very near to actual.

INTRODUCTION
In many industries, ever-increasing demand for high power and high speed with uninterrupted and reliable operation, accurate prediction and control of the dynamic behavior (unbalance response, critical speeds and instability) is increasingly important. The most crucial part of such large turbo machinery is the machine elements that allow relative motion between the rotating and the stationary machine elements i.e. “Bearings”.
Bearings are used in variety of devices, including rotating machinery in the manufacturing industry. Bearing failures account for a large percentage of breakdowns in such machines and can lead to costly downtime. Bearing failure is probabilistic in nature. Because of this, maintenance programs based on set schedules or past performance are not completely effective in preventing failures during operation. Techniques in condition monitoring have been investigated for decades with the aim of determining the actual status of the bearings and replacing them based on that information. We just tried another method for prediction of bearing condition.
Quality is the term which decides the company image and that depends on factors such as Machine Downtime, Good Quality Product and many more. As consideration of competition each and every industry is trying for a good AUTOMIZATION.
1.1 What Is Bearing?
Bearing is a machine part or device which is mostly used when there is a fixture or machine needs rigid support or when there are two revolving or rotating surfaces are there and they are in contact with each other. Bearing helps both the surface to lower the friction and run system smoothly.
