Hi little buddy,
Imagine you have a toy car, and when you push it, it moves, right? But what happens when you don't put anything under it, like a rug or a mat that makes it harder to move?
The wheels of the car would start rubbing against the ground, causing friction, and slowing down the car. Well, the same thing happens with machines that have moving parts, like engines or turbines.
They also have wheels or shafts that turn and need to be supported so they can move freely and without causing too much friction. That's where bearings come in handy.
Bearings are little things placed between the moving parts to make them glide smoothly against each other, reducing friction, and making them last longer.
Think of them as a cushion or a pillow that holds the moving parts and allows them to rotate without having to touch the other machine parts.
They can come in different shapes and sizes, like balls, rollers, or plain bearings (also called bushes). Some are even made of different materials, like metal, plastic, or ceramics.
In conclusion, bearings help machines to move freely and last longer by reducing friction between their moving parts. They are like pillows that support and cushion the moving parts while allowing them to rotate without touching other machine parts.
