Thrust ball bearings are rolling bearings engineered to handle axial loads exclusively. Their design features a shaft washer (tight ring), housing washer (loose ring), and a ball-cage assembly with grooved raceways, enabling efficient axial force transmission with minimal friction. Not suitable for radial loads.
