What Is The Bearing Type Selected For The Bicycle?

The type of bearing chosen for sport bikes varies from model to model and from manufacturer to manufacturer.

Bicycle Bearing Models
Bicycle Bearing Models:

In general, the bearing model number of the front wheel is 6000, and the model number of the rear wheel is 6200, and there is the front wheel bearing model number 608, and the rear wheel bearing model number 6000.

Extended information:

1, bearing bore with the first two digits from the right of the basic code. For the commonly used inner diameter d = 20 ~ 480mm bearing bore is generally a multiple of 5, the two digits indicate the bearing bore size by 5 divided by the quotient, such as 04 said d = 20mm; 12 said d = 60mm and so on. For the inner diameter of 10mm, 12mm, 15mm and 17mm bearings, inner diameter code for 00, 01, 02 and 03. For the inner diameter of less than 10mm and more than 500mm bearings, the inner diameter of the method is otherwise specified, see GB / T272-93.

2, bearing diameter series (i.e., the same structure, the same inner diameter bearing in the outer diameter and width of the change series) with the basic code from the right of the third digit. For example, for centripetal bearings and centripetal thrust bearings, 0, 1 indicates the light series; 2 indicates the light series; 3 indicates the series; 4 indicates the heavy series; 7 indicates the super light; 8, 9 indicates the super light.
