If it is a smaller motor (below 1 1kw), for example, the bearing is below 6308 or 63 1 1, the press-fitting method can be adopted. Sometimes you can directly use square iron and hit the bearing with a hammer. However, when the servo press is used, the bearing can be easily pressed in, and the stress direction of the bearing inner sleeve is relatively uniform.
This method is the safest if it is only used to install bearings by hot fitting. As long as the bearing is heated to about 75℃, it can be installed directly without damaging the bearing inner sleeve.
As for the servo press, it is a pressure device, which will damage the bearing and minimize the bearing.
