How to inspect and accept the goods of split bearing seat

Based on analysis and debate, it is possible to control these bearings to distinguish various technical guidelines and quality indicators of the host machine, and to improve them based on technical means. For example, it is often necessary to know the specific value of the rotational accuracy of a bearing when evaluating whether the rotational accuracy of an imaginary host machine can achieve a specific goal. In assembly processes, it is often necessary to know the shaft and seat hole of the bearing and the shaft on the assembly surface. For the deviation of the sum of linear deviations, the response is installed in a reverse direction, enabling the errors to offset each other, thereby achieving higher spindle change accuracy; In addition, for example, it is often necessary for the assembly workshop to measure the specific dimensions of the INA bearing assembly surface and match them with the actual dimensions of the main machine journal and seat hole, so that the INA bearings of the same batch of main machines can first be more evenly matched, without being too loose or tight, to prevent deformation of the raceway or crawling of the mating surface, which is detrimental to ensuring the rotational accuracy and service life of the main shaft.

Quality inspection and product knowledge are necessary for a large number of customers. For example, the material supply and quality control departments must test that the purchased product bearings are qualified. When the quality of the equipment bearings in the equipment maintenance department occurs, the problem with the components is often based on the inspection of the bearings, The manufacturer of split bearing pedestals determines whether the cause of the problem is due to the bearing handling practices themselves or improper technical departments. It is often necessary to distinguish specific values from various technical guidelines and quality indicators for bearings. Bearing distributors are increasingly entering the bearing industry, operating in industries such as engineering machinery, machine tools, automobiles, metallurgy, mining, kerosene, machinery, electric power, and railways. Based on sustained exploration and practice in the bearing industry, it has resulted in a long-term strategy of being a sole partner for a large enterprise to operate its equipment without worry. The bearing rollers are symmetrical and the inner ring has no ribs. Each row of rollers has a stamped steel plate through connection frame. The retaining ring in the behavior is guided by the inner ring.

In summary, customers must have the following knowledge:

1. What preparations need to be done before the quality inspection of bearing products, and why these preparations need to be done;

2. The inspection conditions, methods, instruments, etc. of the inspection product, and the limits within which the inspection results must be limited;

3. What are the standards for inspecting the commodities included in the international nuclear programme;

4. Which items of bearings should be inspected and why should these items be verified;

5. Bearing products are sometimes too large to undergo 100% inspection, so what sampling plan should be adopted and how many quantities should be selected for inspection to more comprehensively and reliably reflect the quality of all commercial INA bearings, and what criteria should be used to measure the inspection results to determine whether the goods are in a qualified batch or whether unqualified batches should be rejected?

Bearing acceptance is generally divided into three categories, namely:

Routine inspection - General inspection of INA bearings upon arrival.

Routine inspections - dimensions, rotational accuracy, clearance bearings, and residual magnetic strength, related to assembly.

Special inspection - Check the vibration quality, noise quality, and other special requirements of the bearing.
