How about the size of the ball bearing roller?
Two, four numbers and five numbers: from right to left. The first two numbers are the inner diameter code. Of which: 00 indicates that the inner diameter of the bearing is 10mm, and 01 means that the inner diameter of the bearing is 12mm, and that 02 indicates that the inner diameter of the bearing is 15mm, and that 03 indicates that the inner diameter of the bearing is 17mm. More than 04 (including 04), the inner diameter is equal to the number from the right to the left, the first two numbers multiplied by five. For example: the inner diameter of 6201 is: 12mm. 6204 of the bearing bore is: 20mm.
The first rolling bearing codes (based on the new code) bearing models, from intuitive models can determine the bearing size. Type code, which can visually determine the structure type of the bearing (mainly classified according to the shape of the rolling body). Outside diameter code, from the bearing model can only determine the series, and what series of what size?. ISO and the main bearing countries have standards, and all countries follow the ISO standard. Specific parameters need to consult the manual. Width code, and the outer diameter of the series code is basically the same, but also need to consult the manual. Bore Code: the basic code of a bearing consists of three numbers, four digits, five digits, and a slash. One, three numbers: from right to left, the first number indicates the dimension of the inside, the figure is a few, the inner diameter is a few mm. For example: 608 the inner diameter of the bearing is 8mm.
