The axial direction refers to the axis direction of the shaft, and the radial direction is perpendicular to the radial direction of the shaft. Therefore, the axial load of the bearing refers to the load generated in the axial direction of the bearing. In layman's terms, it is the force that pushes the inner ring of the bearing out of the outer ring. The types of bearings in accordance with the ability to withstand the axial load from small to large are cylindrical roller bearing <ball bearing <taper roller bearing <rod end bearing. Among them, cylindrical roller bearings do not bear axial loads at all, and end bearings are specially designed to bear axial loads.
