Stone machinery is an important link in the development of the stone industry. Stone machinery is an indispensable part of the development of the stone industry. Accurate selection of stone machinery can greatly enhance the benefits of stone. Bearings are the "heart" of stone machinery. The quality of the bearing plays a key role in ensuring the normal operation, service life and processing quality of the equipment. So what are the factors that affect the quality of bearings? China Stone Net counts several common influencing factors of bearing quality as follows:


Quality of raw materials: The raw materials of bearings are mainly high-quality bearing steel and electrolytic copper and nodular cast iron used in the production of bearing cages. The quality of raw materials determines the quality of bearings. The main processing materials used for high-quality bearings are: Y15 bearing steel, CCY15SIMn tin-manganese steel, GCY15 vacuum degassed steel, carburized steel, etc. In the purchase, it is recommended to buy a slightly larger stone machinery enterprise, and small bearing production companies in order to reduce costs and make profits, there will be a lack of bearing quality. Bearings that do not meet the standard may cause mechanical losses and safety hazards for the stone factory.


Hot processing technology: The reason why bearings can withstand heavy loads and high speeds in different working environments is mainly because the bearings carry out scientific and reasonable heat treatment processes on the components of the bearings on the basis of ensuring the quality of steel materials during the processing process to ensure hardness Between HRC60-64, the bearing has both high strength and toughness during use, thus ensuring the inherent quality of the bearing. This advanced heat treatment process and equipment are generally not available in small bearing manufacturers and counterfeiters.


Bearing accuracy: The accuracy of the bearing is an important basis for ensuring the quality of the bearing, mainly including dimensional tolerance, rotation accuracy, radial runout, axial runout, clearance size, vibration value. Bearings of various accuracy grades are manufactured in strict accordance with national standards. It has a great influence on improving the processing accuracy and service life of the equipment. Due to the limitation of thermal processing conditions, fake and inferior bearings are often manufactured indiscriminately, cut corners, used inferior quality, impersonated with high precision and low accuracy, and some even counterfeit brand-name trademarks. Without precision, they simply cannot reach the standard of use.


Bearing testing: Bearing testing is a very important part of the bearing manufacturing process, which mainly includes parts in-process testing and overall testing before bearing assembly. It requires professional testing equipment, professional testing personnel and national regulations To complete the testing standards. As a precision standard part, the production process of the bearing is completed under the monitoring mechanism of a complete quality assurance system. Such systems and mechanisms require high costs, and the manufacture of inferior bearings simply does not meet these conditions.
