The quality of single side bearing immediately endangers the length of bearing time. Therefore, when selecting bearings, it is necessary to select the quality of stainless steel plates in many aspects. Whether the material selection is appropriate or not is still a factor that must be considered in the failure analysis of unilateral bearings. The key daily task of bearing failure analysis is to find the key factors that lead to the invalidation of stainless steel plate bearings based on many raw materials, analysis data and invalid methods, so as to purposefully and clearly put forward rectification measures, increase the service life of bearings, and prevent sudden initial invalidation of bearings. The installation standard is one of the main factors in the application factors. The bearing usually changes the bearing force in the middle of each part of the full set of bearing due to improper installation, and the bearing operates under abnormal conditions and is invalid in advance.
According to the technical standards of bearing installation, application, maintenance and repair, the load, speed ratio, operating temperature, vibration, noise and lubrication standards borne by the running bearing shall be supervised and inspected. In case of any abnormality, the cause shall be searched immediately, and the adjustment shall be carried out to recover it.
1. Whether the outer packing box is clear: generally, the well-known brands of Zhengchang have their own professional design schemes, and the staff carry out the design scheme of the outer packing box, and the processing plant that assigns the production and manufacturing standards to pass the customs carries out the manufacturing, so the packaging is clear and unambiguous from the wireframe to the graphics.
2. Whether the anti-counterfeiting mark words are clear: the words and models of well-known brands are printed on the unilateral bearing body. The font style is small, but most of the honorary products of the factory apply anti-counterfeiting mark technology, and the pressing is carried out before the heat treatment process. Therefore, although the font style is small, it is deeply concave and clear. The font style of counterfeit goods is not only vague, because the hot stamping technology is not smooth, and the font style floats on the surface, some of which can even be erased casually.
3. Is there any noise: hold the stainless steel plate bearing body sleeve with your right hand, and turn the coat with your left hand to make it rotate. Listen for any noise. Because the production and manufacturing standards of the vast majority of counterfeit goods are out of date, and they are used in a manual workshop, it is inevitable to mix with debris and other residues in the production process, which are hidden in the body of the unilateral bearing, so there will be a noise when it is rotating. This is also different from the well-known brands that strictly abide by product standards and use equipment.
4. Whether there are muddy oil stains on the surface: this should be paid attention to when choosing stainless steel plate bearings. Because the technology of antirust treatment in China at this stage is not particularly popular, it is very easy to leave thick oil stains when carrying out antirust treatment on single-sided bearing bodies, and the hands are sticky and thick. While the overseas authentic bearings basically do not see the mark of antirust agent, but the insiders who are particularly careful say that the bearings smell like a smell, which must be under antirust agent, just invisible.
5. Is the fillet symmetrical: to put it bluntly, the fillet of the bearing, that is, the junction of the horizontal and vertical surfaces, the fake bearing is not satisfactorily solved in this well ordered position due to the limitation of the production process. The metallurgical industrial quality of raw materials of unilateral bearings used to be the key factor endangering the initial ineffectiveness of overturned bearings. With the development of Metallurgical Technology (such as vacuum pump vacuum distillation of bearing steel, etc.), the quality of raw materials has been improved. The proportion of raw material quality factors in the failure analysis of stainless steel plate bearings has long been reduced, but it is still one of the key hazard factors of bearing invalidity.
