Experimental Study on Vibration Analysis of a Needle Roller Bearing Using Various Grades of Lubricant Viscosity

Abstract

Needle roller bearing is mostly used in rotating machinery, material handling systems, heavy machineries and others due to their low vibration and high load-carrying capacity. In this paper, an experimental setup is developed to illustrate the vibration analysis of needle roller bearing, which is lubricated with oil of six different viscosity grades (ISO 10, 32, 46, 68, 100 and 120). The signal processing methods are used to extract the vibration analysis using parameters, such as acceleration and frequency. Results are obtained by signal processing methods in terms of time series and FFT plots.
