In some aspects of the machine, imported bearings are used because of requirements. Imported bearings are relative to domestic bearings.
Some counterfeit imported bearings have seriously disrupted the bearing market. When buying imported bearings, you must look at the authenticity and introduce the method of distinguishing genuine imported bearings:
1. Under normal circumstances, the imported bearings of the Zhengchang brand have their own dedicated designers to design the external packaging, and arrange the production conditions of the factories for production, so the packaging is very clear from the line to the color block, no Vague, some imported brands have unique designs on their packaging to protect their intellectual property.
Brand words, labels, etc. will be printed on the imported bearing body. The font is very small, but most of the products produced by the factory use steel stamping technology and embossing before heat treatment. Therefore, although the font is small, it is deep and very clear. The fonts of counterfeit products are not only vague. Because of the rough printing technology, the fonts float on the surface, and some can be easily erased by hand.
2. Specially careful experts say that imported bearings smell a smell, it must be anti-rust oil, just can't see it.
3. Listen to the bearing inner sleeve of the imported bearing on the left, and turn the jacket with the right hand to rotate it to hear if there is a noise. Due to the backward production conditions of most counterfeit products and complete manual workshop operation, impurities such as sand will inevitably be mixed in the production process and hidden in the bearing body, so it will make noise when rotating. This is the biggest difference from a genuine brand that strictly enforces production standards and is machine-operated.
4. The chamfers of imported bearings are even, the so-called chamfers of imported bearings, that is, the intersection of horizontal and vertical surfaces, due to the limitation of production technology, counterfeit imported bearings are not handled in these corners Satisfactory, and the chamfer of real imported bearings is even and smooth.
