What is the function of a bearing in machinery?

The function of a bearing in machinery is primarily to reduce friction between moving parts and support loads. Bearings are designed to facilitate smooth movement by providing a low-friction interface between rotating or sliding components. When machinery operates, such as in motors or rotating shafts, the parts create friction when they come into contact with each other. Bearings mitigate this friction, allowing for increased efficiency and longevity of the components involved.

Additionally, bearings help to stabilize and support the loads applied to rotating parts, ensuring that machinery operates reliably and effectively under various conditions. By maintaining proper alignment and reducing wear, bearings play a crucial role in the overall performance and durability of mechanical systems.
