To guarantee that a shaft bearing system operates safely and reliably, the bearings' condition must be monitored on a regular basis. Bearing and shaft failures are thought to be the leading reasons of failure in various revolving machines used in the industry at highre and lower speeds. The condition of the bearing changes throughout use, so do the vibrations, and their characteristics vary depending on the reason. As a result, the bearing's unique property makes it suited for vibration monitoring and other procedures. The vibration measurement approach may reliably anticipate the upcoming failure and life of a mechanism or component based on changes in vibration signals.  \nAs a result, the bearing's unique property makes it suited for vibration monitoring and other procedures. The vibration measurement approach may reliably anticipate the future failure and life of a machine or component based on changes in vibration signals. As a result, the goal is to extend the machine's life by detecting faults early on, allowing for an effective maintenance program to be implemented to remedy the problem. Subsequently, this research uses machine learning methods to detect bearing problems, compare them to various faulty and standard models, and categorize the bearing type. In this research work, we use outer race fault data from the Bearing data set to extract the time domain features from the dataset using Various machine learning models, including Principal Component Analysis, K-NEAREST NEIGHBOURS (K-NN), SUPPORT VECTOR MACHINES (SVM), RANDOM FOREST CLASSIFIER, DESICION TREE, and LOGISTIC REGRESSION. As a consequence, we obtain the best model that performs optimally on the data set. Finally, the proposed methods of condition monitoring will be implemented in a realworld case study of the shaft bearing system. Thus, vibration testing is used to monitor the state of the shaft bearing system, allowing for the identification of problematic bearings and improved performance after they are replaced.  \nKeywords: Bearing fault diagnosis using machine learning technique , Bearing condition monitoring  \nI. INTRODUCTION  \nPreviously, maintenance was exclusively referred to as breakdown maintenance (also known as run-to-failure), which occurs after a machine or component fails. This type of maintenance requires little planning. Then, preventative or periodic maintenance was formed as the following maintenance plan. Regardless of the physical asset's condition, this maintenance plan entails doing maintenance chores on a regular basis. Finally, the condition-based maintenance technique (also known as predictive maintenance) was developed. This maintenance technique  \nuses data acquired from several condition monitoring systems to guide maintenance operations. Condition-based maintenance reduces unnecessary maintenance effort by performing maintenance only when there is evidence of aberrant behavior of the machine component or device. If the condition-based maintenance program is properly established and implemented, it is possible to minimize maintenance costseven further by avoiding unnecessary preventive maintenance procedures. Rotating machine element vibration analysis isone of the most commonly used devices in condition monitoring activities. Analyzing and measuring the extent of vibration in rotary machines allows you to find various issues such as misalignment, looseness, bent shaft, unbalance, cracked shaft, motor fault, gear fault, rubbing, and impellor or blade defects. However, the defects listed above are fairly common in high-","cbCaiheAgffKXU3V","https://ap.wps.com/l/cbCaiheAgffKXU3V","pdf",1979591,1,6,"English","en",105,"# Abstract\n# Introduction\n## Maintenance strategies and predictive maintenance\n## Vibration analysis in rotating machines\n# Condition Monitoring Principle","[{\"question\":\"Why is condition monitoring important for shaft-bearing systems?\",\"answer\":\"Bearing condition changes over time, affecting vibration characteristics.
