On the basis of way to provide the carrying capacity, we recognize radial hydrodynamic bearings and hydrostatic bearings. Hydrodynamic bearing are the elements of machines which works under elasto-hydrodynamic lubrication conditions. Due to radial clearance journal bearings have self induced vibrations. There is trend of monitoring different machine components with the help of data generated by vibration by these components for ensuring their reliable and effective working. Bearing vibration analysis is becoming popular for monitoring bearing performance. This study deals with vibration and tribological analysis for different bearings. The bearings are normally used components in machinery for a wide range of applications. Bearing is a mechanical element which permits relative motion between two parts, also used to support the shaft and takes up forces acting on shaft. It is crucial part of any rotary components and its failure causes disastrous failure of machinery. In this work, performance of hydrodynamic journal bearings with different groove geometry is investigated. This work carried out with two helical, three helical grooves and non-groove (plain) bearings, tested at radial load and RPM are mottled within specified range an experimental vibration signals were obtained. The bearing shows different behavior for different loading and speed conditions with same groove locations. Vibrational analysis is the effective tool for monitoring the conditions of bearing before they get failed. The vibration signal analysis has been carried out in Frequency domain by FFT analyzer. Results obtained by experimentation were in amplitude versus speed. The tribological performances of plain, two groove and three groove journal bearings were investigated in this dissertation work. Several experiments were performed under different static loads by using pin on disc tribometer. The tests were conducted at different speed and different loading conditions. The results were in the form of coefficient of friction.
