A batch of bearings has arrived recently, and they tend to get damaged frequently. I hope experts can help by assisting in determining whether these bearings are genuine or not
To check whether a bearing is genuine, one can start by examining the following aspects: 1. Packaging: Genuine bearings usually come with clear labeling, including the brand logo and model number, and their packaging is neat and professional. 2. Material and construction: Genuine bearings are made of high-quality materials, have a smooth and delicate surface, clear markings, and are free of burrs or defects. 3. Marking: Check whether the production batch number, brand, and other information on the bearing match the official information provided by the brand. 4. Sound: The bearing should rotate smoothly without any abnormal noises; fake products may produce irregular friction sounds. 5. Ask the supplier: Find out about the supplier’s reputation and purchasing methods, and choose a reliable supplier. It is recommended to seek help from a professional mechanical engineer or the purchase source for a more accurate assessment. .
There are specialized testing institutions that, after conducting tests, issue official and authoritative reports. If the product quality does not meet the standards, this report can be used as evidence to file a claim against the supplier
It is possible to inquire about the sourcing channels; nowadays, branded bearings are all distributed through authorized partners in various regions. It’s problematic if it wasn’t purchased from an authorized dealer, as the brand headquarters doesn’t care either. But there are also domestic brands that are in disarray internally and sell fake products themselves (you can search for reports on these manufacturers online).
Apart from quality issues, the damage to bearings is mainly due to problems with maintenance work and proper upkeep. For example, axial force, the levelness of the equipment, coupling alignment, dynamic balance, and whether the lubricant or grease used contains impurities. Additionally, factors such as related seal leaks are also causes of bearing damage. It is recommended to send a device diagram indicating the location of the bearings, along with an analysis of the reasons, for reference.
Originally, fake imported bearings could be detected by their smell, but now it’s unclear
