During the installation process of the full complement cylindrical roller bearing, some matters should be paid attention to to ensure accurate installation. If the installation is not good, it will affect the service life and working effect of the bearing. So, what are the precautions for the installation of cylindrical roller bearings? What should we do before, during and after installation? The following is a detailed introduction to its six major precautions: 1. It must be installed in a dry and clean environment. The processing quality of each component should be carefully checked before installation. All mating surfaces must be carefully cleaned and deburred, and unmachined surfaces of castings must be free of sand. 2. Before installation, it should be cleaned with gasoline or kerosene, used after drying, and ensure good lubrication. Bearings are generally lubricated with grease, but can also be lubricated with oil. 3. During installation, an equal pressure must be applied to the circumference of the end face of the ferrule, and the ferrule must be pressed in. Do not hit it directly with tools to avoid damage to the bearing. 4. In the case of small interference, the end face of the bearing ring can be pressed with a sleeve at room temperature, and the sleeve can be hit with a hammer head, and the ring can be pressed in evenly through the sleeve. For mass installation, hydraulic presses can be used. When pressing in, it should be ensured that the end face of the outer ring and the end face of the shoulder of the shell, and the end face of the inner ring and the end face of the shaft shoulder are pressed tightly, and no gap is allowed. 5. When the amount of interference is large, it can be installed by oil bath heating or sensor heating bearing method. The heating temperature range is 80℃-100℃, and cannot exceed 120℃. At the same time, tighten the bearing with nuts or other suitable methods to prevent the bearing from shrinking in the width direction after cooling and causing a gap between the ring and the shaft shoulder. 6. After installation, a rotation test should be carried out. First, it should be used for the rotating shaft or bearing box. If there is no abnormality, it will be operated with power without load and at low speed, and then gradually increase the rotation speed and load according to the operation conditions, and detect noise, vibration and temperature. If the abnormality is found, it should be stopped and checked. It can be delivered for use only after the running test is normal.
