433 - What is the role of bearings in machines?
Imagine you're on an ice-skating rink, and you're gliding smoothly across the ice. That's basically what bearings do in machines. They help moving parts slide smoothly and easily, with less friction.
Bearings are small rings or balls that sit between moving parts in a machine, like a wheel and an axle. They help:
- Reduce friction: Bearings make it easier for the parts to move, so they don't get damaged or heat up.
- Make movement smooth: They help the parts move in a straight line, without wobbling or shaking.
- Increase efficiency: By reducing friction, bearings help machines use less energy and work more efficiently.
Think of it like ice-skating – with bearings, machines can "glide" smoothly and easily, just like you do on the ice!
