What problems should be paid attention to when rolling bearings are installed? 

Pay attention to the device orientation of the angular touch bearing. The angular touch bearing has an elliptical touch area and only accepts axial thrust in one direction. When the bearing is installed in the opposite direction, because the steel ball is on the edge of the raceway, a groove-shaped wear zone will appear on the loaded surface. Therefore, you should pay attention to the correct device orientation when installing.What problems should be paid attention to when rolling bearings are installed?
