Is it fake?
Thread Content
After installation and operation for about 24 hours, there was no problem with alignment and correction, and there was no shortage of lubricating oil. The oil temperature continued to rise during operation.
Without lubricating oil, the high-speed rotating beads are deformed.
Isn’t the high-temperature lubricant used?

It is subject to the requirements of the equipment installation instructions. Such as the required coupling clearance, horizontal (vertical), parallelism, axial thrust factors,,,,,,. Installation issues are most likely. For reference. It is recommended that the video should include the overall and partial structure of the equipment.
Don’t always make fake products. It is found that some users are super irresponsible, distort the facts, or even ignorant and immoral. When something goes wrong, you immediately dump the supplier. Why don't you ask yourself how you use it?
It is doubtful that there are many fake rolling bearings. Not only world-famous brands, domestic manufacturers also have fake products, which is why the members of the HZ team were sentenced and the factory closed down. But identifying fakes requires skill. Where to buy from? What are the markings on the bearings? Genuine brand goods are authentic with the logo, model and production * * . How to use other bearings of the same model purchased by Kuli. I have been dealing with fakes over the years.
If there is a lack of oil, the cage, balls, inner ring, and outer ring will all have color changes caused by high temperature. From the photos, there is no color change on the outer ring. Judging from the two photos, it should be the rotating shaft of the single-stage cantilever centrifugal pump. There should be a gap between the two 73 series bearings responsible for positioning.
The set of bearings on the side of your photo are non-stressed bearings. 1. Check whether the bearing installation clearance meets the standards. 2. Is there any problem with this equipment before? Is the axial force too large? 3. Is the oil level filling normal?
