Grit Pump Bearing Life

In daily gravel pump maintenance, when we overhaul the gravel pump, we need to replace accessories, and most of them will also replace the bearings. Even if the bearings are not worn or damaged, they will be replaced habitually. So why is this and is this approach worth recommending?
In fact, the life of a bearing is determined by the number of hours it works, which is determined by the bearing load, the number of rotations and the lubricant the bearing receives.
When the bearing works on the shaft, the load is transferred from the inner ring to the outer ring of the bearing through the balls. When rolling under load, each ball bears a portion of the pressure. It is this stress that will eventually fatigue metal components.
When the gravel pump is in operation, the loads on the bearings are primarily the weight of the rotating assembly, stresses caused by the interference fit on the shaft, any bearing preload specified by the manufacturer, and a small amount of radial force and Axial force.
