(1) Do a good job in rolling mill bearing data statistics Do a good job in rolling mill bearing use and damage data statistics, find out the common problems of rolling mill bearing damage rules, so as to accurately and specifically propose rolling mill bearing consumption reduction measures.

    It can be recorded from the following aspects:

    1. The design and precision of the rolling mill;

    2. The implementation of rolling products and process changes;

    3. The lubrication effect of lubrication and sealing;

    4. On-site conditions such as mill adjustment and transmission;

    5. On-site conditions such as the accuracy of bearing assembly parts, assembly and disassembly conditions;

    6. The form of bearing damage and the location of the installed machine.

(2) The strength of each part of the bearing should match. In the case of ensuring the strength of the bearing box (that is, the good rigid support of the rolling mill bearing), try to choose a rolling mill bearing with a large load capacity. In addition, the size of each part of the rolling mill bearing should be optimally designed according to the application conditions to ensure that the strength of each part of the rolling mill bearing is equal and maximize the service life of the bearing. For example, where the wear and deformation of the bearing box is large and the outer ring of the bearing is often broken, the wall thickness of the outer ring of the bearing can be thickened to reduce the diameter of the rollers, and the strength of the outer ring can be enhanced to achieve the longest bearing life.

    (3) Use of high-quality bearing materials. Due to the existence of non-metallic inclusions, especially oxide inclusions, the strength of the bearing material is weak, causing stress concentration and causing premature fatigue damage to the bearing. Therefore, vacuum degassing or electroslag remelting of bearing steel can be used. Although the unit price of the bearing is high, the bearing damage is less, the operating rate of the rolling mill is improved, and the overall cost should be reduced.

    (4) Precision, clearance and fit of rolling mill bearings.
