How does a precision bearing steel ball make the bicycle moving?

- Feb 14, 2019-

Everyone rides a bicycle or a motorcycle. Everyone knows the precision bearing steel ball in the wheel. Generally, the bearings of the bicycle are 6200, 6201, 6202, 6000, 6002. The number of steel balls is generally 7-9.

The bearings allow our machines to function properly. If there are no bearings, we may need to replace those parts that are prone to wear frequently.

The principle of the bearing is very simple: the object is easier to roll than to slide. Car wheels are like large bearings.

If a sled is used instead of a wheel, it is much more difficult for the car to advance on the road.

This is because when the object slides, the friction between the two objects produces friction that slows down the sliding speed. But if the surfaces of the two objects can roll against each other, the friction will be greatly reduced.

Each rolling precision bearing steel ball used in the bicycle can be simply divided into a Palin bearing and a bead bearing.

Bead gears are made up of bowls, shafts and intermediate balls. They form a large bearing together with the hub. Since the cages do not need to be used like industrial bearings, the same size bead gear can accommodate more. Many precision bearing steel balls, and each bearing steel ball has a large contact area and can withstand greater pressure.
