Verified Answer
Which part of a vehicle reduces friction between axle and wheel?How do...
Ball bearings are used to reduce the frictional force between the wheels and the axle. Here small hard steel balls are placed between the wheel and the axle which are free to rotate. This way instead of the wheel sliding on the axle which will create sliding friction, the balls rotate between the wheel and the axle thereby causing rolling friction which is much lower than sliding friction.
This will reduce wear and tear to a large extent.
