1. Is the outer packaging clear

In general, reputable manufacturers have their own dedicated designers to design the external packaging and arrange factories with qualified production conditions for production. Therefore, the packaging of the product should be very clear and unambiguous, from lines to color blocks.

2. Is the steel stamp clear

Each bearing product will have its brand name, number, etc. printed on the bearing product body. Although the font is very small, products produced by legitimate manufacturers use steel stamp technology for printing, and are pressed before being overheated. Therefore, although the font is small, it is deeply recessed and very clear. Usually, the font of counterfeit products is not only blurry, but also due to rough printing technology, the font floats on the surface, and some can even be easily erased by hand or have serious hand marks.

3. Are there any turbid oil stains on the surface

We should pay special attention to whether there are cloudy oil stains on the surface when purchasing imported bearings. Due to the gap between the current rust prevention technology in China and advanced manufacturing countries abroad, it is easy to leave thick oil stains when rust prevention treatment is carried out on the bearing body. When touched by hand, it feels sticky and thick, while there are almost no traces of rust prevention oil on bearings imported from foreign countries. According to industry insiders, those who are particularly attentive can smell a special odor on imported bearings, which is the smell of rust proof oil.
