What is the primary purpose of using ball bearings in turbine engines?

The primary purpose of using ball bearings in turbine engines is to minimize rotational friction. Ball bearings allow smooth and efficient movement between rotating components, which is crucial in the high-speed environment of a turbine engine. By reducing friction, ball bearings facilitate smoother operation, enhance performance, and contribute to the overall efficiency of the engine. Lower friction means less energy is wasted as heat, allowing the engine to operate more effectively and with reduced wear over time.

While supporting the weight of the engine, maintaining temperature, and enhancing fuel atomization are important considerations in turbine engine design, they are not the primary functions of ball bearings. Ball bearings specifically excel at reducing friction, which is vital for the reliability and longevity of turbine components in high-performance applications.
