Before installation, clean the bearing housing, shaft, and other mating parts to remove oil and impurities, and ensure there are no burrs or burrs. Ensure that the inner diameter of the bearing housing meets the outer diameter of the bearing, and that the shaft journal meets the required tolerances. When installing the inner ring, ensure that the rolling elements are not subjected to stress. Gently tap the inner ring end face with a plastic hammer until the inner ring end face is fully in contact with the mating end face, as can be determined by the sound. When installing the outer ring, refer to the inner ring installation instructions. RV reducer bearings must be installed in pairs. During assembly, the customer adjusts the bearing preload. Proper preload ensures optimal bearing rigidity after assembly, allowing the bearing to withstand loads in all directions, including bidirectional axial force, radial force, and overturning moment.
