Machine components are the individual parts that make up a machine, each serving a specific function to ensure the machine operates effectively. Common components include gears, bearings, motors, and pulleys. These parts work together to convert energy into motion or perform tasks, such as lifting, moving, or processing materials. Understanding machine components is essential for maintenance and repair. Each component must be compatible with others to ensure smooth operation. For example, gears must mesh correctly, while bearings reduce friction between moving parts. Proper selection and installation of these components can enhance a machine's performance and longevity.
