What is famous will present fake goods; the same is true for imported bearings; in order to prevent you from preventing economic losses caused by fakes; today we are notified how to distinguish and import original bearings and copies of imported bearings.
First, let's start with the color of imported bearings <br> Let's first look at the color of imported bearings; see if the color is greenish. Why? Because of the steel constraints of the bearing itself; small bearing manufacturers and shoddy imported bearings mostly use ordinary steel, carbon steel, Ma Steel, and even some use of iron pipes. The appearance of these materials is mostly white; and the special bearing steel The color is greenish. So our first step should be from color. Of course; the color is unreliable; because there are many external factors that will affect the external color of the imported bearings; so we have to Aspects to identify and identify.
Second, the need to check whether the outer packaging of the imported bearings can be clear <br> Under normal circumstances; the bearing brand of the normal track manufacturers; are personally depicted by the depiction of the external packaging; and will organize the production conditions of the factory to carry out Manufacturing and production. Therefore; the packaging of imported bearings; from the line to the color block; are very clear; not ambiguous.
Then we have to investigate whether the stamp of the imported bearing can be clarified.
Usually bearing information on the bearing, typeface, label, etc. will be printed on the bearing body of the imported bearing. Although the font of the stamp is very small; but because of the bearing products produced by the normal track bearing manufacturers; all use the professional stamping skills; Before passing through the heat treatment; it was pressed. So the font is not the same as the font of the counterfeit product, although the font of the counterfeit product is not vague; and because the printing skills are rough; Floating on the outside; some or even easily can be erased by hand.
Third, we still have to see if the imported bearings can have noise. <br> How to distinguish whether the imported bearings can have noise? The method is very simple; we can use the left hand to grasp the inner sleeve of the imported bearing; then use the right hand to move the jacket to make it rotate; to hear if it has noise, because the production conditions of most counterfeit products are backward; thorough craft workshop operation; In the process of producing bearings, impurities such as sand will be incorporated; they will be hidden in the bearing body; so when you rotate the bearing, the noise will be announced. These noises; and the manufacturers who strictly enforce the production specifications and operate with the machine The biggest difference between the produced brand products.
Fourth, look at the appearance of imported bearings can have dirty oil traces <br> This point should be taken care of when purchasing imported bearings. Why? Because the current domestic anti-rust skills for bearings and the international anti-rust skills are still very far away. Therefore, the impromptu imported bearings are very simple to leave a thick trace of oil when the anti-rust treatment of the bearing body; I will feel sticky and screaming.
Foreign imported bearings; all the traces of anti-rust oil can not be seen on the whole. But it does not mean that there is no anti-rust treatment; but you can't see it. If you don't believe, you can pick it up and smell it; To a taste; this taste is the taste of anti-rust oil.
5. Pay attention to whether the chamfer of the imported bearing can be evenly <br> The so-called chamfer of the bearing; that is, the intersection of the horizontal and vertical faces of the bearing. The counterfeit imported bearing is bound by the production skill; The disposal of other parts will appear unsatisfactory.
The above is how the difference between the original imported bearings and the copy of the imported bearings should be focused on; expectation can lead us to focus; do not let the impersonating imported bearings drill holes.
Recommend to friends comments close window Bearing related knowledge "The principle of the disassembly of the tapered bore rolling bearing" is what is the device of the cylindrical inner bore bearing. The use of the inserted roller bearing is the use of the super-precision of the imported bearing.
