Roller bearings are important components that support the roller and maintain its correct position in the rack. The requirements for roller bearings are small friction coefficient, sufficient strength, small deformation, long service life, and easy roll replacement. The working characteristic of roller bearings is to withstand very high unit loads, which is due to the considerable rolling force to be borne within a shorter roll neck. Roller bearings can be divided into two types: one is sliding bearings, and the other is rolling bearings.
The roller bearing is an important component used to support the roller and maintain its correct position in the frame. The friction coefficient of bearings is related to the rolling energy consumption; The service life of bearings is related to the utilization rate of rolling mills; The stiffness of bearings has a certain impact on the dimensional accuracy of rolled products. Therefore, the production of steel rolling requires that the roller bearing should have a small coefficient of friction, sufficient strength, and a certain degree of stiffness. In modern rolling mills, the structural modeling of roller bearings should also facilitate rapid roll changing operations.
Roller bearing is an important component of a rolling mill, and its assembly, adjustment, and maintenance quality have a direct impact on bearing life, product dimensional accuracy, and rolling mill operation rate. Many early damaged roller bearings are not due to their own quality problems, but are caused by improper installation and lack of good maintenance. Maintenance work is a difficult and meticulous system engineering, involving many knowledge of steel rolling technology, hydraulics, machinery, and so on. Careful maintenance and strict management are of great significance for prolonging the service life of bearings and giving full play to their good performance.
