How to determine the size of bearing housings
First of all, determine the required bearing type, size, and then according to relevant standards, you can find the corresponding bearing seat size.
Determine the bearing size, such as "bearings of the outer diameter, height, diameter, outer diameter, is to choose the corresponding bearing seat of the internal diameter, height corresponding to the bearing seat in the width of the internal diameter, compared to the bearing seat of the shaft hole size."
Bearing model, from the model intuitive, you can determine the size of the bearing.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.Internal diameter code:A basic bearing code consisting of three digits, 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.Two, four numbers and five numbers: from right to left. The first two numbers are the inner diameter code.Among them:00 indicates that the inner diameter of the bearing is 10mm,01 indicates that the inner diameter of the bearing is 12mm,02 indicates that the inner diameter of the bearing is 15mm,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.
