The importance of four-row cylindrical roller bearings of Rolling mill and the precautions for installation and use

Rolling mill is an important equipment for copper plate and strip production. Four-row cylindrical roller bearings for rolling mills are the main components of rolling mills and the main guarantee components for high-speed and high-precision cold rolling system processes. From the 1980s to the present , Four-row cylindrical roller bearings for rolling mills have been widely used in non-ferrous metallurgical industry enterprises, and there are many doubts about precise application and application processing in practical applications. Mainly: how to develop the effective life of four-row cylindrical roller bearings for rolling mills, and how to reduce the damage to the precision of rolling materials. This is particularly good for copper plate and strip production and processing enterprises under construction, small and medium-sized copper plate and strip production and processing enterprises, and enterprises that have greatly expanded their copper plate and strips but have insufficient application processing methods and skills.

Due to the weak comparison of the technical ability and kinetic energy of this enterprise, the understanding of the four-row cylindrical roller bearing for rolling mills is relatively shallow, and there are many doubts in the equipment, application and application management of four-row cylindrical roller bearings for rolling mills; The service life is short, and cold-rolled products are often affected by the doubts of rolling bearings, which greatly harms the probability of mechanical equipment opening, the maintenance cost of machinery and equipment, and the labor efficiency of maintenance staff.

Therefore, how to improve the accurate understanding of the four-row cylindrical roller bearing for rolling mills, and how to improve the effective application and application of four-row cylindrical roller bearings for rolling mills seems to be more and more urgent. According to the summary of personal experience in the practical operation of copper processing enterprises, there are mainly the following doubts in the application and application management system of four-row cylindrical roller bearings for rolling mills.

① Four-row cylindrical roller bearings for Rolling mills are treated the same as general rolling bearings, and there is no special application method.
②Cut other user groups in the rolling bearing casually to destroy the bearing clearance.
③Rolling bearing machinery and equipment are rude, crooked, and rudely smashed.
④The smoothness is not standard, especially the way of thin oil smoothness, too smoothness is not optimistic.
⑤It can be used with rollers and seated bearings, and the backlash precision is reduced.
⑥The maintenance of rolling bearings is not timely, and the application method is not appropriate.
⑦ There is no precise matching scheme and backlash standard for rolling bearings of new machinery and equipment.
⑧ The rolling bearings are unreasonably inspected and inspected in the factory.
⑨ The overweight of the Rolling mill equipment is not optimistic, and the life limit of the rolling bearing is reduced.
