  • Radial and axial load capacity of rolling bearings

    What does radial and axial load capacity mean? The radial force is the force acting perpendicular to the shaft axis. Radial ball bearings optimally absorb forces acting perpendicular to the shaft axis. The axial force acts in the direction of the axis, meaning along the axis, of a body. Optimally, axial ball bearings absorb large forces that act in the direction of the shaft axis.
