Bearings are mechanical components designed to reduce friction between moving parts while supporting rotational or linear motion. They enable efficient energy transfer, minimize wear, and extend the lifespan of machinery. Key types include:  
- Ball Bearings: Use balls to separate races (inner and outer rings), ideal for high-speed applications like electric motors.  
- Roller Bearings: Utilize cylindrical rollers for heavy radial loads, common in gearboxes and conveyor systems.  
- Needle Roller Bearings: Compact design with thin rollers, suited for limited-space applications.  
- Tapered Roller Bearings: Handle combined radial and axial loads, used in automotive wheel hubs.  
- Spherical Roller Bearings: Self-aligning, tolerating misalignment in industrial machinery.  

Applications: Bearings are critical in automotive systems, aerospace, wind turbines, robotics, and more. Their performance depends on material quality (e.g., chrome steel, ceramic hybrids), precision manufacturing, and lubrication. Standards like ISO and ABMA ensure compatibility and reliability. Proper installation and maintenance further optimize efficiency and durability.
