It is not an exaggeration to refer to bearings as the joints of a car. In a car, not only the wheels need to be equipped with bearings, but any machine component that undergoes transformation also requires the participation of bearings. It is a very inconspicuous but very serious thing in the transmission system. Due to the large workload and high wear, replacing bearings is a common task in car repairs. Here are several common methods for distinguishing bearing quality:

Whether the outer packaging is clear: Usually, there are dedicated personnel to depict the outer packaging of the original brand, and factories with qualified production conditions are organized to manufacture it. Therefore, the packaging is very clear and unambiguous in terms of lines and color blocks. Some imported brands also have a common description on their accessory packaging specifically designed to protect personal intellectual property rights, which will be continuously analyzed in the following content.

Is the steel seal clear: there will be brand words, labels, etc. printed on the bearing body. The font is very clear. The font of counterfeit products is not only vague, but also because the printing skills are rough, the font floats on the surface, and some can even be easily erased by hand.

Is there any noise: Hold the inner sleeve of the bearing with your left hand and rotate the outer sleeve with your right hand to listen for any noise. Due to the outdated production conditions of some counterfeit products and the thorough manual workshop operation, impurities such as sand are inevitably mixed into the bearing body during the production process, causing noise to be announced during rotation. This is the biggest difference between genuine factory brands that strictly adhere to production standards and operate with machines.

Whether there are dirty oil stains on the surface: this should be a common concern when purchasing imported bearings. Because the current anti rust skills in China are not yet fully developed, it is easy to leave thick oil stains on the bearing body during anti rust treatment, which is sticky and sticky when held in hand. However, there is hardly any trace of anti rust oil on imported bearings from abroad. However, experts who are both careful say that imported bearings smell like they have been coated with anti rust oil, and they cannot see it.

Whether the chamfer is uniform: The so-called chamfer of the bearing refers to the intersection of the horizontal and vertical surfaces. Counterfeit bearings, due to the constraints of production skills, are not handled satisfactorily in these corner areas.
