Angular contact ball bearings feature offset inner and outer raceways designed to handle combined loads (simultaneous radial and axial forces). Because a radial load creates an axial force, they must be assembled with a preload and are typically mounted in pairs, trios, or quartets to ensure structural rigidity.
