Atmospheric air always contains moisture: the higher temperature, the higher humidity is typical for the air. However, when compressed air is accumulated moisture, the water is condensing on the internal parts of the equipment and pneumatic systems.

Beware of all kinds of fake bearings

Replacing bearings for machinery equipment in general and air compressors in particular in order to ensure durability and increase the time to use machinery equipment, minimize risks in the production process, we should replace genuine bearings.

Recently, there are many types of Bearings (SKF - SKF Ball Bearings) at very cheap prices to hit consumers' psychology, most of these products are fake.

Currently, Thanks to advanced graphics techniques, illegal manufacturers around the world have also made packaging very similar to genuine SKF packaging, increasing the likelihood of confusion for customers. Through censorship, product quality is poor.

Some of the most common techniques are :

+ Using iron, carbon steel (not enough hardness), recycling old bearings (not high precision) to make bearings.
+ New but low-quality bearings are printed, engraved with the label (letters) on the bearings to turn into bearings and put into imitation packages, like real packages
+ Used bearings, recycled, then sold to the market with no clear signs of being recycled.
+ Buy bearings at small factories and then affix the brand name.
+ Use poor quality fake for genuine bearings.
+ Mixed real and fake goods.
+ Selling fake goods if customers want to buy cheap ones and higher prices for the genuine.
