Expert Buyer’s Guide to What is a Bearing: 6 Key Types for 2025 Industrial Needs
Abstract A bearing is a fundamental machine element engineered to constrain relative motion to a desired range and to reduce friction between moving parts. Its primary functions are to support and guide rotating or oscillating components, such as shafts and axles, while transferring loads between different parts of a machine. By facilitating motion with minimal resistance, bearings enhance operational efficiency, precision, and speed, thereby reducing energy consumption, heat generation, and component wear. The operational principle can involve either rolling or sliding contact. Rolling-element bearings utilize balls or rollers to minimize friction, making them suitable for high-speed applications requiring precision. In contrast, plain bearings rely on a sliding motion, often over […]
