In the field of industrial manufacturing, many will be applied to bearings. The bearing quality of bearing manufacturers on the market also varies widely. Imported bearing manufacturers and domestic bearing manufacturers emerge in endlessly, so how can we distinguish the quality of bearings when we buy bearings? 1. Judging by the printing on the surface of the bearing Since the performance of the bearing depends to a large extent on the material of the bearing, the selection of the bearing material is very important when purchasing the bearing. Many bearings on the market are mainly made of steel materials, so steel materials are the key point to judge the quality of bearings. Generally speaking, we can judge by the printing effect of the bearing. If the steel printing on the bearing is very clear, it means that it is a qualified steel bearing. On the contrary, if the printing on its surface is fuzzy, it means that it may be counterfeit and inferior. Product, not worth buying. Sanli’s 37-year-old bearing manufacturer’s production process, the bearings produced are all made of high-precision imported steel, not only clear printing, but also high temperature resistance, corrosion resistance, and strong contact fatigue, wear resistance, hardness , rust resistance, etc., very good. 2. Listen to the sound to judge the purity of the bearing material. When listening to the sound, we can hold the inner sleeve of the bearing with one hand, and turn the bearing sleeve with the other hand to hear whether it is the sound. If the bearing has noise, it means that the bearing manufacturer has mixed impurities such as sand when producing the bearing, and regular merchants will not do this. 3. Look at the surface stains to determine the anti-rust performance of the bearing. In the production process of bearing manufacturers, there is usually an anti-rust treatment link, and the anti-rust technology in this link directly determines the quality of the bearing. If the bearing is rusty in the hand, the quality of the bearing is not very good; if the surface of the bearing looks smooth and bright, this is a better bearing, indicating that the bearing manufacturer's technology is relatively strong, so The bearing life will be longer. Therefore, when purchasing, customers must observe carefully. Sanli has 37 years of experience in production and research and development among domestic bearing manufacturers, and it can stand the test of the market in terms of printing, rust prevention, and purity! Only when the torque is accurate can the rotation be stable! (http:///helps/zjsl.html)
