When the bearing is installed, equal pressure must be applied on the circumference of the ring end face to press the ring in, and no tools such as pins should be used to knock directly on the bearing end face in order to avoid damaging the bearing. In the case of small interference, the end face of bearing ring can be pressed by sleeve at room temperature, and the sleeve can be equally pressed by sleeve by tapping sleeve with a head. Hydraulic press can be used when installing in large quantities. When pressing in, it should be ensured that the outer ring end face and the shell shoulder end face, the inner ring end face and the shaft shoulder end face are pressed tightly, and no gap is allowed.
