    The correct installation method of insulated bearings involves multiple steps to ensure that the insulation and mechanical properties of the bearings are optimally utilized. Here are some key steps:
    1. Check the bearings before installation: Check whether the packaging is intact. If there is any damage, carefully check whether the insulation layer of the bearing is damaged. If this type of bearing is damaged, its insulation capacity is greatly reduced, and it is easy to be corroded by current and lose its insulation effect; 2. Check the matching size of the insulated bearing and the rotor shaft: When assembling the motor, carefully check the matching size of the bearing and the rotor shaft during bearing installation, as well as the matching size of the bearing outer ring and the end cover hole; 3. Cleaning before installation: Before installing the bearing, check the relevant components to ensure that they are clean. Do not open the original packaging of the bearing until the moment before installation. Remove burrs, chips, rust and dirt on the installation surface, otherwise, the bearing will generate noise and vibration when working; 4. Use special tools to install and remove bearings: Avoid damage to insulated bearings due to improper tools and operation. For example, the copper rod knocking method during installation may cause uneven axial force of the bearing, deformation of the cage and damage to the rolling element, so professional bearing removal tools must be used. 5. Control the amount of oil in the bearing and bearing seat: Too much oil in the bearing and housing will cause the rolling element of the bearing to slip, and the rolling friction will change from rolling friction to sliding friction, thereby damaging the rolling element of the bearing. Therefore, the amount of oil should be controlled to avoid too much or too little. 6. Pay attention to ensure the insulation function: For bearings with insulation design on the outer ring, it is necessary to ensure that the insulation is intact. If the bearing insulation is damaged during the installation process, the thin oil film of the bearing will be broken down by the shaft voltage, not only will the lubrication condition of the rolling element deteriorate, but the generated electric sparks will cause electrical corrosion to the rolling element of the bearing, causing the surface of the rolling element to be unpolished and accelerate the wear of the bearing. Choose the appropriate installation method: For the installation of cylindrical bore bearings, for small bearings with interference fit (D<=100mm), the bearings can be pressed onto the shaft or housing by mechanical or hydraulic methods. For larger bearings (D>100mm) or when the interference is large, the principle of thermal expansion and contraction can be used for installation. Generally, oil bath heating or electric induction heating is used. The installation of tapered bore bearings with tapered inner holes is installed by interference fit. By following these steps, you can ensure the correct installation of the insulated bearing, thereby extending its service life and maintaining good insulation properties.
