37 years of bearing manufacturers teach you: how to choose grinding machine spindle bearings-

There are many fields where bearings are used are various machine tools and grinding machines. Many customers of our grinding machines will ask, there are many grinding machine spindle bearings on the market, how should we choose? Sanli concludes that the selection of grinding machine spindle bearings generally follows the following four considerations: 1. Speed ​​and temperature rise; the speed of many grinding machine spindle bearings is getting higher and higher, so in these application scenarios, the stability of the bearing is also higher. The higher the requirements, the grinding machine spindle bearing will be accompanied by a certain degree of temperature rise during operation. This temperature rise will also affect the speed of the bearing. In general, we need to select the appropriate bearing type according to the application scenario. Matching mode, lubrication mode, the performance of the grinding machine spindle bearing can be improved. 2. The life and carrying capacity of the main shaft bearing of the grinding machine; Whether the main shaft bearing of the grinding machine can maintain the accuracy determines the life of each component of the main shaft of the grinding machine to a certain extent. The bearing capacity of the bearing is very important for heavy grinding machines and so on. 3. Rigidity and shock resistance of the grinding machine spindle bearing; For the normal operation of the grinding machine, it is necessary to ensure the normal rigidity of the grinding machine spindle, otherwise the accuracy of the bearing will have a relatively large error, and even vibration will occur, and the shock resistance of the grinding machine spindle is precisely due to the grinding machine Determined by the rigidity of the main shaft and the bearing, we can effectively increase the rigidity of the bearing by preloading the bearing, thereby improving the shock resistance of the main shaft. 4. Noise level. The main source of grinding machine noise is the noise from the grinding head bearing during the high-speed operation of the grinding machine, so we should choose low-noise grinding machine spindle bearings. Only when the torque is accurate can the rotation be stable! To learn more about grinding machine spindle bearings, please visit: http:///product_mczzzc.html
