The load exceeds the SKF bearing is the main reason that cause bearing damage, corrosion, most likely to develop into corrosion of rolling bearings, early wear and fatigue of the sources of pollution, waste serious fatigue damage cause bearing.
In general, the main causes of SKF bearing rolling contact fatigue damage of the metal surface of rolling bearing. Therefore, for the specific application, based on rolling fatigue is enough, selection of rolling mill bearing and the appropriate size. The international standard ISO281 is the fatigue of the metal rolling contact surface as the base. But more important, should do, some of which may be part of the cage, lubrication and seal, the durability of the SKF bearing its life cycle plays the same role as the leading role, in some cases, a complete bearing system. Theoretically speaking, when all the components to achieve the same life, is the ideal working life. In other words, bearing life calculation to realize the actual work and life, the part of the working life, the calculation must be at least the bearing life.
Said the size and nature of the rated load SKF load bearing by using rolling bearings, its value exceeds the rated load bearing, such as size, direction of the bearing load, the load is a one-way or two-way, will cause the bearing fatigue damage. SKF bearings on the bearing equipment regular maintenance, operation and peripheral parts replacement was disassembled for inspection, attention should be paid attention to in order to judge bearing dismounting times of rolling mill bearing parts can use and record the use of good from bad again.
