A bearing is a mechanical component that enables smooth movement between two parts, typically by reducing friction. It supports rotating or moving elements, allowing them to move freely while maintaining alignment.

Bearings are commonly used in various applications, including:

Automobiles: In engines, wheels, and other moving parts.
Industrial Machinery: In motors, conveyors, and pumps.
Home Appliances: In washing machines and fans.
Aerospace: In engines and landing gear.
Overall, bearings are essential for enhancing efficiency and longevity in mechanical systems.
