What is axle spindle bearing?

The axle spindle bearing is a single row angular contact ball bearing consisting of a solid inner ring, an outer ring, a ball, and a cage assembly with a solid window cage. They are not removable. These bearings can be open or sealed.

The axle spindle bearing has limited tolerances. They are particularly suitable for bearing arrangements that require very high guiding accuracy and speed capability. They are particularly suitable for bearing arrangements of shafts in machine tools.

The correct configuration of the axle spindle bearing refers to the combination of bearing types and the arrangement of the front and rear bearings. Different configurations determine the different load capacity, running speed, stiffness, temperature rise and service life of the machine tool spindle, especially the stiffness and temperature rise. The influence is more significant, so the spindle bearings should be reasonably arranged according to the requirements of the working characteristics of the machine tool. The purpose of the running-in operation is to make the rollers and the raceway pass through the running-in before the bearing is officially turned, so as to have good contact conditions, so as to keep the bearing with good contact accuracy, and to avoid the bearing at high speed and low speed at the beginning. Heavy-duty use will cause 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 end face of the roller and the shoulder of the inner ring. If the contact conditions are not good, the phenomenon of occlusion damage is easy to occur, so more attention should be paid to the running-in operation of this type of bearing. The axle spindle bearing is the spindle bearing of precision machine tools and similar equipment, which ensures the working accuracy and performance of precision machine tools.
