The role and requirements of bearing clearance
The presence of clearance in the bearing is to ensure that the bearing can be operated flexibly and without blockage, but at the same time it is required to ensure that the bearing runs smoothly, the axis of the bearing does not significantly settle, and the number of rolling bodies that bear the load is as much as possible. Therefore, the bearing clearance has a great influence on the dynamic performance (noise, vibration and friction) of the bearing and the rotation accuracy, and the bearing capacity of the service life (wear and fatigue).
