bearing design is a crucial aspect of engineering that involves creating components to support rotating shafts or axles. Key considerations include load capacity, friction reduction, choice of bearing type, materials selection, geometry, sealing and lubrication, environmental factors, manufacturability, and application-specific features. An effective bearing design aims to provide efficient load support, minimize friction and wear, and ensure durability and reliability in diverse mechanical systems. Engineers use advanced tools and methodologies to optimize bearing designs for specific applications and performance requirements.
