　　What do you think about the specifications, models, and dimensions of bearings?

　　1. The inner diameter of the bearing is represented by the first and second digits from the right of the basic code. For bearings with a commonly used inner diameter of d=20-480mm, the inner diameter is generally a multiple of 5. These two digits represent the quotient obtained by dividing the inner diameter size of the bearing by 5. For example, 04 represents d=20mm.

　　2. The diameter series of bearings (i.e. the series of changes in outer diameter and width of bearings with the same structure and inner diameter) are represented by the third digit from the right of the basic code. 0 and 1 represent the ultra light series; 2 represents the light series; 3 represents the middle series; 4 represents a heavy series.

　　3. The width series of bearings (i.e. the series of changes in the width of bearings with the same structure, inner diameter, and diameter series) are represented by the fourth digit from the right of the basic code. The diameter series code and width series code are collectively referred to as the size series code.
