The high-precision d3182100 series

The high-precision d3182100 series bearing can adjust the radial clearance, ensure the transmission without clearance, and keep the accuracy stable for a long time. The double row roller gives this kind of bearing high rigidity and high bearing capacity. The short cylindrical roller bearing has good kinematic performance, so that the allowable limit speed is high, so as to ensure small heat output and low temperature rise. Therefore, it is often used to bear radial force in the spindle structure which requires high precision and high rigidity. The high-precision c2268132 double row thrust ball bearing is used to bear the axial force. The inner diameter and outer diameter of the bearing are matched with d3182132 bearing, and the inner spacer is used to adjust the optimal preload. In this way, it saves a very troublesome adjustment process compared with the installation method of two sets of thrust centripetal ball bearings or groove ball bearings in the past. At the same time, because the ring flange of the two-way thrust ball bearing bears the centrifugal force of the steel ball better than the "flat" groove of the groove ball bearing, the bearing is also suitable for higher speed. The combination of the above-mentioned main shaft bearings, with the advantages of low noise and long service life, has been more and more adopted in the main shaft structure.
