  • Maximum Capacity Ball Bearings (High Radial Load,

    Heavy duty bearing types such as 6200 or 6300 series may take axial loads of up to 50 percent of the static radial load rating. Thin-section deep groove ball bearings can only support axial loads of between 10 and 30 percent of the bearing's static radial load rating due the shallower raceways. Please note, these figures are based on pure axial load. Additional radial loads or moment (misalignment loads) will have an impact on the axial load capacity.
