What are the standard imported bearing in production applications

Imported bearing what are the standards in the production practice believe we all know, large production machinery has cast iron base plate, the plate is capable of supporting bearings, imported bearings can use the form of separation, may in the actual installation, in different situation, the processing fee is thus increased. But because the bearing manufacturers are widely used for the mass production of standardized, it will lead to the low price, also can increase the cost of offset process. May be because the cause of the material, imported bearings are made in cast iron, must adopt the method of bearing and support separate, that is to say, bearing is a separate sheet is tasted, such processing is simple a lot. Bearing at the time of production, stents and bearing want to make it into a part is very difficult to make out the bearing is not enough, and the quality of the bearing can't see it directly, and it is going to the attention of relevant departments, strengthen the management of the bearing quality, improve the application of standard bearings. Generally between the imported bearing and the bearing support is not in this way, but it depends. If the bearing is installed on the ground or installed on the wall, this is all need certain process, the size of the base plate and the stent to hold good.
