More than INA bearing load is the main cause of bearing damage, corrosion of corrosion are most likely to develop into rolling mill bearing, is the early wear and fatigue of pollution sources, severe fatigue damage can lead to bearing scrap.
In general, INA bearing metal on the surface of the rolling contact fatigue of the main causes of damage of rolling bearing.
Therefore, for a particular application, based on the rolling fatigue is enough, to choose the appropriate rolling mill bearing and size.
International standard ISO281 is metal fatigue of rolling contact surface as a foundation.
But more important, should do, which may be part of the cage, lubricant and seals, INA bearing the durability of its life cycle in the same role, because in some cases, the leading role, a complete bearing system.
In theory, when all the components to achieve the same life, is the ideal working life.
Bearing life calculation, in other words, to achieve the practical work of life, its part of work life, must be at least the calculation of bearing life.
INA bearing rated load with the rolling mill bearing load of the size and nature, said the numerical exceed rated load bearing, such as the size and direction of the load, the load bearing suffered by the one-way or two-way, can cause bearing fatigue damage.
For bearing equipment preventive maintenance, and peripheral parts replacement operation were removed, INA bearing to check bearing dismantling of the matters needing attention should be paid attention to need, in turn, determine whether time rolling mill bearing parts can be used again and record the usage of good from bad.
