Bearing the identification method

Currently on the market too many imported bearings fake, the face of many fake and shoddy products, how should we identify the authenticity of imported bearings? First: the packaging is clear: Under normal circumstances, are the factory brand has its own special The designer designs the package and arranges the production at the factory where the production conditions have passed so that the package is clear and unambiguous, both from the line and from the color block. (Part of the imported brand accessories packaging also has a unique design to protect their intellectual property). Second: whether the clear lettering: the bearing body will be printed on the brand words, labels and so on. The fonts are very small, but most of the products produced by the factory use stamping technology, and are pressed before being heat-treated. Therefore, the font size is small but deep and very clear. The fake fonts not only fonts, due to rough printing technology, fonts floating on the surface, and some even easily can be erased by hand. Third: whether there is noise: hold the bearing body sleeve left hand, right hand toggle the coat to rotate, listen to it if there is noise. Since most of the counterfeit products have poor production conditions and completely hand-operated workshops, it is inevitable that impurities such as sand will be mixed in the production process and hidden in the bearing body, so the noise will be spun during rotation. This is the biggest difference between a manufacturer's brand and a machine manufacturer that strictly enforces production standards. Fourth: the surface is turbid oil: This should pay special attention to the purchase of imported bearings. As the current domestic anti-rust technology is not particularly home, so the bearing body rust treatment is easy to leave thick traces of oil, sticky in the hands of sticky, and imported bearings almost no look To the traces of rust-proof oil, it touches particularly careful expert said that there is a smell of imported bearings, it is certainly anti-rust oil, just can not see it. Fifth: Chamfer is uniform: the so-called bearing chamfer, that is, the intersection of the cross-section and the vertical, fake bearings due to production technology constraints, parts of these corner corners are not handled satisfactorily. FAG bearing bearings imported bearings and maintenance methods introduced in order to ensure FAG bearings can be normal and long-term operation, we need regular FAG bearings for maintenance and repair. Today we will introduce you to some problems in this area, I hope for your help. Maintenance of FAG bearings, maintenance, and exception handling In order to maintain the original performance of the bearing in good condition as long as possible, maintenance and repair to prevent accidents in the first place, to ensure the reliability of operation and improve productivity and economy . Maintenance of the best corresponding mechanical operating conditions of the operating standards, on a regular basis. The contents include the inspection of operational status, replenishment or replacement of lubricants, periodic disassembly. As a maintenance item in operation, there is bearing rotation noise, vibration, temperature, lubricant condition, and the like. FAG bearing damage and countermeasures in general, if the proper use of bearings, you can use to reach the fatigue life. But there will be accidental premature damage, can not tolerate the use of the situation. This early damage, as opposed to fatigue life, limits the quality of use known as failure or accident. Many due to the installation, use, lubrication of the attention, invasion from the outside of the foreign body, the shell, the thermal effects of the study is not sufficient and so on. FAG bearing damage on the state, such as: roller bearing ring flange injury, as a reason to consider, inadequate lubricants, not suitable for oil and gas structure defects, invasion of foreign bodies, bearing installation error, the axis of the flexible Music is too large, there will be overlap of these reasons. For more information in this regard, please refer to the "FAG bearing damage and measures to prevent the" article introduction. Therefore, it is hard to know the true cause of the damage only by investigating the bearing damage. However, if you know the use of bearings machinery, the use of the structure around the bearings to understand the situation before and after the accident, combined with Kawamoto bearing damage and inspection of several reasons, we can prevent the recurrence of similar incidents.
