What is the function of a bearing in machinery?

To increase friction between moving parts
To reduce friction and support rotating shafts
To connect electrical circuits
To transmit motion between components

The correct answer is: To reduce friction and support rotating shafts

The function of a bearing in machinery is to reduce friction and support rotating shafts. Bearings are designed specifically to facilitate smooth movement between two surfaces, allowing one part to revolve around another with minimal resistance. This is crucial in various applications as it enhances the efficiency and longevity of machines. By minimizing friction, bearings help in decreasing wear and tear on the machinery, improve energy efficiency, and promote smoother operations. Additionally, bearings provide radial and axial support to rotating shafts, which prevents misalignment and maintains the proper functioning of the machinery. This support is vital for the stability of the components involved in any rotating assembly. In essence, bearings play a critical role in ensuring that mechanical systems run effectively and can endure the stresses presented by their operational environment.
