Bearing surface

Okay kiddo, let me explain to you what a bearing surface is.

Imagine you have two toy cars that need to move or roll next to each other - but they can't touch each other. There must be a small space between them so they don't create friction and slow down. This space is called a bearing surface.

It's like when you are on a ride at the amusement park and the wheels are spinning, there must be a small gap in between the wheel and the track, so the wheel can spin freely without touching the track. This gap is the bearing surface between the wheel and the track.

Bearing surfaces can also be found in machines and engines. For example, when the crankshaft rotates in a car engine, it must create a gap between the crankshaft and the engine block to avoid friction and damage. This gap is the bearing surface.

In summary, a bearing surface is a small space between two surfaces that helps them move or rotate without touching each other, reducing friction and damage.
