Bearing model basic code by the bearing type code, dimension series code, constitute diameter code. E.g:
6201,6 representation type code; 2: Dimension series code; 01: diameter code
1, bearing type code
Bearing type code numbers or letters, as follows:

2, size series code
Bearing size series code combination bearing width (height) of the series code and diameter series code from.
Refer to the corresponding series of the same diameter of the bearing bore diameter size range. Respectively 7,8,9,0,1,2,3,4,5 etc outer diameter sequentially increasing diameters series.
Refer to the corresponding width of the series bearing the same diameter series width dimension series. Respectively, 8,0,1,2,3,4,5,6 etc. width dimension in ascending order of the width of the series.
Thrust bearing series corresponds to the width to height series radial bearings with 7,9,1,2 etc. height dimension in ascending order of height of four series.
3, diameter code
As follows:

Examples
|
|
|
0.6 to 10mm (non-integer)
|
With nominal inner millimeters directly represented,
In the series between the base and the size of the code with "/" separate |
Deep groove ball bearings 618 / 2.5
An inner diameter of 2.5mm |
|
|
1 to 9mm (integer)
|
With a nominal inside diameter of a few millimeters directly represented,
Deep groove ball bearings and angular contact ball bearing diameter series 7,8,9, Between the inner diameter series code with "/" separate |
Deep groove ball bearing 605 or 618/5
An inner diameter of 5mm |
|
|
10 to 17mm
|
10mm
12mm 15mm 17mm |
00
01 02 03 |
Deep groove ball bearings 6003
An inner diameter of 17mm |
|
20 to 480mm (except 22,28,32)
|
Nominal inside diameter of 5 divided by the quotient, quotient digits,
Need to add "0" in the left quotient, such as 08 This is the kind of the more common way to represent :) |
Spherical roller bearings 23208
An inner diameter of 40mm |
|
|
Greater than and equal to more than 500mm
And 22,28,32mm |
With nominal inner millimeters directly represented,
But in between the size of the series with the "/" separate |
Spherical roller bearings 230/600
An inner diameter of 600mm Deep groove ball bearings 62/28 An inner diameter of 22mm |

Various types of bearings have a corresponding representation, and has a corresponding law standards, the user should calculate the appropriate parameters according to the corresponding bearing bearing models!
