The size determination of Processing Of Bearing Inner And Outer Rings involves multiple factors. The following is a detailed explanation of the size determination method of Processing Of Bearing Inner And Outer Rings based on the information of the reference article:
1. Determination of inner diameter size
Bearings with a diameter less than 10mm:
The inner diameter size of the bearing is the inner diameter code of the bearing.
Bearings with a diameter between 10mm and 17mm:
The inner diameter size is represented by a specific code. For example, the inner diameter code of a bearing with an inner diameter of 10mm is "00"; the inner diameter code of a bearing with an inner diameter of 12mm is "01", and so on.
Bearings with a diameter greater than or equal to 20mm and less than or equal to 180mm:
The calculation formula for the bearing inner diameter is: multiply the last two digits of the bearing basic code by 5. For example, in the bearing model "21307CDE4", "07" is the inner diameter code, and the actual inner diameter size is 07×5=35mm.
2. Determination of outer diameter size
Determined by bearing model:
The bearing model usually includes information such as the inner diameter, outer diameter and width of the bearing. However, it should be noted that the bearing models produced by different brands may be different, so when searching, the model information provided by the original manufacturer should be used as much as possible.
Determined by measurement:
If there is no bearing model or the model information is uncertain, the outer diameter of the bearing can be determined by measurement. The specific steps include: select a caliper, clear the caliper scale and open the bottom, place the bearing on a flat surface, press the inner ring of the bearing with your hand, place the bottom of the caliper on the outer ring of the bearing, and read the value on the caliper to get the outer diameter of the bearing.
In summary, the size determination of Processing Of Bearing Inner And Outer Rings requires comprehensive consideration of multiple factors such as the bearing model, inner diameter code, outer diameter calculation formula, and measurement method. When selecting and replacing bearings, ensure that the size of the inner and outer rings matches the equipment requirements to ensure the normal operation and service life of the bearing.
