I. Measurement of bearing outer diameter

Measurement of bearing outer diameter belongs to the category of relative measurement, need to use special tools to carry out, generally using internal and external ferrule measurement or electronic vernier measurement methods.

How can one measure the outer diameter of a 球軸承?

1. Internal and external ferrule measurement method

The method is to put the bearing between the inner and outer ferrules for measurement. The specific steps are as follows:

(1) Select the inner and outer ferrules corresponding to the outer diameter of the bearing, and place the bearing on the inner ferrule.

(2) Put the outer ferrule around the bearing and adjust the clamping strength of the outer ferrule so that it can hold the bearing and cannot be squeezed and deformed.

(3) Measure the distance between the inner and outer ferrules, i.e. the outer diameter of the bearing.

2. Electronic Vernier Measuring Method

This method utilizes the electronic vernier to measure the outer diameter of the bearing, the specific steps are as follows:

(1) Fix the electronic vernier on the measuring device and adjust the zero point according to the instruction manual to make it coincide with the reference size.

(2) Place the bearing on the measuring table of the measuring device.

(3) Stabilize the electronic vernier, make it contact with the bearing, and then read the data on the digital display to obtain the bearing outer diameter size.

II. Precautions

When measuring the outer diameter of the bearing, pay attention to the following points:

1. Choose suitable measuring tools and methods to ensure the accuracy and reliability of the measurement.

2. The bearing should be placed smoothly during measurement to avoid external interference and bearing deformation.

3. In the internal and external ferrule measuring method, the external ferrule should not be loosened or squeezed to avoid affecting the measuring results.

4. In the electronic vernier measuring method, the measuring device and electronic vernier should be kept clean and sensitive.

5. Measurement should be recorded when measuring values, and archived for future inquiries and comparisons.

Measurement of bearing outer diameter need to take relative measurement method, internal and external ferrule measurement method and electronic vernier measurement method are two commonly used methods. In the measurement, attention should be paid to the use of appropriate tools and methods to ensure the accuracy and reliability of the measurement. At the same time, the measured values should be recorded and archived for future use.
