Precision spindle bearings include precision angular contact ball bearings 70 series, 719 series, 72 series, precision cylindrical roller bearings N10 series, NN30 series, precision ball screw support bearings TAC series, FAGQJ348N2MPA bearings.
The correct configuration of spindle bearings refers to the combination of bearing types and the arrangement of front and rear bearings. Different configurations determine the different load capacities, operating speeds, stiffness, temperature rise and service life of the machine tool spindle, especially the impact on stiffness and temperature rise. It is more obvious, so the spindle bearings should be reasonably configured according to the requirements of the machine tool's working characteristics. The purpose of the running-in operation is to ensure that the rollers and raceways of the bearing have good contact conditions through running-in before the bearing is officially angled, so as to maintain good contact accuracy of the bearing and avoid the bearing initially operating at high speed and speed. Heavy load use causes damage to the rollers and raceways, thereby improving the life and accuracy of the bearing. Since the tapered roller bearing is not in complete rolling contact, there is sliding between the roller end surface and the shoulder of the inner ring. If If the contact conditions are not good, it is easy to cause bite damage, so more attention should be paid to the running-in operation of this type of bearing. Spindle bearings are spindle bearings for precision machine tools and similar equipment. They ensure the working accuracy and performance of precision machine tools.
Ball screw bearings for FAG are a high-precision, high-load capacity mechanical component. Due to their unique design structure and precise processing technology, they are widely used in aerospace, automobiles, machine tools, motors and other fields. It converts axial rotational motion into axial linear motion through the principle of rolling bearings. It has the advantages of high precision, high speed, high load-bearing capacity, and wear resistance, and is favored by engineers.
Ball screw bearings for FAG come in many types, the most common of which is ball screw bearings. It consists of several basic components: outer ring, inner ring, balls and cage. In the rolling state, the balls can withstand relatively complex axial and radial loads. At the same time, because the gap between the balls and the cage is extremely small, the rolling friction coefficient is extremely small and durable.
In addition, Ball screw bearings for FAG not only have high precision and high load-bearing capacity, but also can accurately transmit rotational motion, so they are widely used in many occasions. For example, in machine tools, ball screw bearings can accurately control the position of processing tools and ensure high-precision processing.
