What is the main purpose of bearings?

The main purpose of bearings is to reduce friction between moving parts. In mechanical systems, bearings allow for smooth rotation and linear motion by providing a low-friction interface between surfaces. This reduction in friction is crucial for improving the efficiency of machines and prolonging their lifespan, as it minimizes wear and tear on components.

By allowing parts to move freely with less resistance, bearings help in maintaining the performance of machinery, enhancing its operating efficiency, and reducing the energy required for movement. This is especially important in applications such as motors, wheels, and various other mechanical systems where consistent motion is essential for functionality.
