Industry 4.0 represents a paradigm shift in industrial manufacturing through the integration of cyber–physical systems, Internet of Things (IoT), cloud computing, and advanced data analytics. Among the most impactful applications of this transformation is predictive maintenance (PdM), which leverages machine learning (ML) and data-driven models to predict equipment failures before they occur. Predictive maintenance minimizes unplanned downtime, reduces maintenance costs, improves asset reliability, and enhances operational efficiency. This paper presents a comprehensive review of predictive maintenance within the framework of Industry 4.0, focusing on the role of machine learning techniques in fault diagnosis, remaining useful life (RUL) estimation, and condition monitoring. Various ML approaches, including supervised, unsupervised, and deep learning models, are discussed along with their industrial applications. Case studies from manufacturing, energy, and process industries are reviewed to demonstrate practical implementation. Challenges related to data quality, model interpretability, cybersecurity, and scalability are also addressed. Finally, emerging trends such as physics-informed machine learning, digital twins, and edge-AI are explored, highlighting future research directions for intelligent maintenance systems in smart industries
