What is the machine tool spindle bearing?

Jiaxing bearing factory plant in 1950, has more than 60 years of bearing production experience, the production of machine tool spindle bearing with high speed, high precision, strong carrying capacity, high voltage, high temperature resistant characteristics. Spindle bearing as the name implies is to use on the machine tool spindle bearings, bearing factory in jiaxing remind everyone in the process of machine tool spindle bearing selection need to pay attention to the following: 1. Rotation speed and temperature rise along with the development of science and technology, machine tool spindle speed is more and more high, speed range is more and more big, therefore, is becoming more and more high to the requirement of bearing high speed stability. The temperature rise of the machine tool spindle bearing is an important factor to limit bearing rotating speed. Typically, correct selection of bearing types and tolerance grade, the configuration way, clearance ( Pre-load) , lubricants and lubrication method, such as size, can to a certain extent, improve the high speed performance of rolling bearings. 2. Life and carrying capacity for general machine tools, the life of the spindle components is mainly refers to the use of the term to keep the spindle precision, thus, the precision of the bearing is asked to keep the performance to meet the requirements of the spindle component life. For heavy duty machine tools or strong cutting machine, should first consider the bearing capacity. 3. Rigidity and vibration resistance to ensure the quality of machine tool processing, must make the main shaft system has enough rigidity, otherwise it will cause greater error or even flutter. Vibration resistance is refers to the resistance of forced vibration and self-excited vibration. Spindle component vibration resistance depends on the main shaft and the bearing stiffness and resistance. The preloaded roller bearing can effectively improve the stiffness of the spindle system. 4. Noise in high speed grinding machine, grinding head bearing noise is the main component of the whole machine noise, should choose low noise rolling bearing.
