The general bearing inner diameter code indicates the method as shown in the table below.
Bearing inner diameter / mm Inner diameter code description Example
0. 6 to 10 (decimal) The inner diameter (mm) is directly indicated; but the inner diameter is separated by a "/" between the scale series 618/25 d=2. 5mm
1 to 9 (integer) The inner diameter (mm) is directly indicated; but the inner diameter is separated by a "/" between the scale series 618/5 d=5mm
10 to 17 Internal diameter code 0 01 02 03 6201 d=12mm
Inner diameter / mm 10 12 15 17
20 to 480
(22, 28, 32 outside)
1. Multiply the inner diameter code by 5 equal to the inner diameter (mm).
2. The inner diameter (mm) divided by 5 is equal to the inner diameter code;
Merchant: 10 vacancies with "0"; such as 06
222006 d=30mm
Greater than and equal to 500 or
22,28,32
The inner diameter (mm) is directly indicated; but the inner diameter is separated by a "/" between the scale series 230/500 d=500mm
62/28 d=28mm
