How to quickly judge the bearing quality of bearing manufacturers?

In the field of industrial manufacturing, many will be applied to bearings. The bearing quality of bearing manufacturers on the market is also very different. Imported bearing manufacturers and domestic bearing manufacturers emerge in an endless stream. So, when we buy bearings, how can we distinguish the quality of bearings? 1. Judging by the printing on the bearing surface Since the performance of the bearing depends to a large extent on the material of the bearing, the selection of the bearing material is critical when purchasing a bearing. Most of the bearings on the market are mainly made of steel materials, so steel materials are the key to judging the quality of bearings. Generally speaking, we can judge by the bearing printing effect. 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 the surface is blurred, it means that it may be counterfeit and inferior. Product, not worth buying. The 37-year production process of bearing manufacturers, the bearings produced are all made of high-precision imported steel, which not only has clear printing, but also has high temperature resistance and corrosion resistance, and also has strong contact fatigue, wear resistance, hardness, Rust resistance, etc., is very good. 2. Listening to the sound of the broken bearing material purity When listening to the sound, you can grab the bearing body sleeve with one hand, and turn the bearing sleeve with the other hand to rotate, and listen to whether it is a sound. If there is noise in the bearing, it means that the bearing manufacturer has mixed impurities such as sand in the production of the bearing, and the regular business will not do this. 3. Look at the surface stains to determine the anti-rust performance of the bearing. In the production process of the bearing manufacturer, there is usually an anti-rust treatment process, and the anti-rust technology in this link directly determines the quality of the bearing. If the bearing is rusted in the hand, the quality of the bearing will not be very good; if the bearing surface looks smooth and bright, this is a better bearing, indicating that the bearing manufacturer's craftsmanship is relatively strong, so The bearing life will be longer. Therefore, when purchasing, customers must observe carefully. It 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! The torque is accurate, in order to turn stable!
